8 minutes into this video and he still hasn't addressed the problem posed here. give me strength!

All your explaining made it much more complicated than it was!

Just a few steps here. First get the price of the shirt before sales tax 8.82/1.05 = 8.40 Next 8.40 is 80% of the original price so divide 8.40 by 8 to get 10%($1.05) and times the result by 10 to get the original price = 10.50

First step: set your variable to be whatever the problem is asking for. That should be the first step in any word problem. This problem asks you to find the original price of the shirt. Hence, x = the original price of the shirt. Second step: Construct your equation. Since there's a 20% discount, the sale price is 80% of x, or 0.8 * x The sale price plus sales tax is (0.8 * x) * 1.05. This equals the price Sara paid: $8.82 So your equation is (0.8 * x) * 1.05 = $8.82. Third step: get the left side of the equation to be just x. Divide both sides by 1.05, and you get 0.8x = $8.82/1.05 = $8.40 Divide both sides by 0.8, and you get $8.40/0.8 = $10.50 Double checking: If the original price is $10.50, then the sales price is $10.50 * 0.8 = $8.40 Add sales tax: $8.40 * 1.05 = $8.82. That's the price Sara paid, so the answer checks out. BONUS TIP: If division by a decimal freaks you out, you can convert it to a fraction. Dividing by 0.8 is the same as dividing by (8/10). That's the same as multiplying by (10/8). Many people find $8.40 * (10/8) easier to handle than $8.40 / 0.8, even though they're the same thing. 🙂

Love all your advice and tips. Great teacher.

MR. TabletClass Math ,thank you for an awesome video/lecture on Algebra Percent Word Problem. Students must do many word problems, for a full understanding of the subject.

DUDE GET TO THE POINT

His explanation was for any IQ of a person who may be desiring to know how to figure it out. I suffered a T.B.I. about 14 years ago. And even though I was sure about some steps, I still desire to see everything explained to congratulate myself on things I still know and I desire the full explanation on anything that I may not have known. So I say job well done John, ?, thanks for the confirmation on the stuff I was convinced that I had right.

Awesome video can you make a calculus video i learned allot from you functions,algebra and Calculus etc...

I use rule of three for this .. if 8.82 its the 105% how much would be 100% so 100*8.82 then divide by 105 thats 8.4 without tax or whats the same but without percents 8.82*1 divided by 1.05 = 8.4. then I use rhe same rule to get the 100% from the 80% that I paid, so if 8.4 is the 80% how much was 100% , 8.4*100 then divide that with 80 and you get the price wiithout discount 10.5

Please what software and device do you use when presenting your Lessons.?

Watching from Philippines. I don't like math but I have to learn it for me to pass the exam. Please more videos for those lower thinking or low learner like me. I have poor understanding about math problem. I want explanation lower than basic or short cut explanation that easy to remember . Thanks for sharing this video.

x + 5%x =8.82 x = discount price before tax Now plug x into this formula: x = y - 20%y y = original price before tax ($10.50)

I saw Sarah @ Good Wheel Bargains. That's Y it was inexpensive. Great explanation-could have been boiled down a bit.

11 minutes in, and he just got to the equation.

How do we retain the skills we learn associated with math if we aren't using them regularly? After I learn something in math, I always forget how to do it later in life if I am not regularly using it.

Yup it's 10.50! Math checks out.

First subtract out the sales tax then add back in the 20% right? Or vice versa

Two easy steps here .. 1) The $8.82 she paid includes 5% sales tax 8.82 = 105% 100 x 8.82 / 105 = 8.40 The sale price of the shirt was $8.40 2) The shirt was 20% off in a sale .. so $8.40 is 80% of the original price 8.40 x 100 / 80 = 10.50 The original price of the shirt was $10.50

$8.82/1.05=$8.40 = price with no tax. $8.40/.8=$10.50 = price before discount and sales tax.

Original price including or excluding tax ? the question is ambiguous.

I like to assume that it cost 100 dollars : 100 ----> 20 -------> 80 ( after 20% off ) ----------> 4 -----------> 84 ( after adding 5% ) x...............................................................................................8.82 so now we can use proportion : x = 8.82 * 100 / 84 x = 882 / 84 x = 10.50

i can understand you more than my teacher 🧠

10.50

Final price is $ 8.82 including 5% tax. $8.82 - 5% = $8.38,,,,, (100% - 20% = 80%), so if 80%=$8.38 then 100%= $10.47 The original price of the shirt is closer to $10.47. in business pennies count.

so x = (8.82) / (1.05) y = x / (0.8) in this (case) dividing was easier when i knew i could use a calculator

Could you cut the waffle and get to the point.

I wasn't going to leave a comment, but now I can't help myself. I laughed when I saw how many people were also feeling the same way. This video needs to be simplified or removed. If I were a kid in grade school and had hours worth of homework to get done , I'd be pissed that I spent nearly 30 mins trying to figure out what the heck your talking about. I'm catching up on math so I can pass an exam for an apprenticeship program and this was way too much for me , I can't imagine how the kids feel. If anything this was more confusing than helpful. Thank you anyway for your time and effort. I give this video a D- .

Bro get to the point.

It's the end of the day and I decided I would do this one with the calculator. And what do you know, I got it right. Now let's learn the method.

8.82/1.05 = 8.40 /.8 = 10.50

was the sales tax on rebated purchase or on original price? if item has a 5 percent tax after reduction. shirt was 10.54 i calculated for a total price 8.85! oops , yes 10.50

I’m more confused now than I was when I started.

I got the answer right, but without making the equation (which I am not Good at

Another take on this, what is the mistake? 8.82 x 0.95 = 8.379; 8.379 / 80 * 100 = 10.473

its funny, i know how to answer but i dont understand the why. how did you figure out the 80% why must we divide the .84 into the full price, will brushing off percents really answer that?

8.82/1.05=.80p where p is the price of the shirt. That's the equation. 8.40 is the discounted price before tax and 10.50 was the original price.

(8.82/1.05)/.8=$10.50

Let x = original price x. = 100% 8.82 = (80% of x) + (5% of 80% of x) Where sale price of the 20% discount is (100-20) * original price 5% Tax of the sale price = 5% * (100-20)* original price

With my calculations I come up with 10.47375

Can the answer be 10:58

How about the sales tax??!! The shirt was originally on sale for $11.025!!

$10.50 = orig price 8.82/1.05 give sale price net of sales tax That #\.8 grosses that # up to orig ask price above

This is worthwhile. I think that students should be exposed to more word-problems, because that is the only way that they come "in-the-real-world".

Verbal diarrhea answer

11.25$

Go to time 11:26 to see beginning of solution to problem. The beginning of these videos are always a bunch of mumble jumble.

Of course the “original price” of the shirt is not what Sara would have paid if it were not on sale. If she expects to get the shirt for 10.50 when it is not on sale, she is mistaken. Don’t forget the 5% (in this case) sales tax.

Trail and error second try $10.50 . First try was 10.00 but 10-20% =8 plus 5% was only 8.40 so upped the anti to 10.50 and bingo.

Where did Sara find a $10 shirt? That's my kinda girl

I did it without algebra just going backwards with ratio. If 8.82 is with 5% taxes then it’s 105% of the price without taxes so 8.82 divided by 105, times 100=8.4. This is with 20% discount so it’s 80% of the original price. 8.4 divided by 80, times 100=10.50. Voila

No algebra solution: Deduct 5% tax from $ 8.82 to find the discounted price before tax, then add 20% to get the original price.

The original price of the shirt is $10.88 cents.

DUDE! First step: 8.82 = 105% of what number. 8.82 divided by 105 = 8.40 Second step: 8.40 is 80% of what number. 8.40 divided by 80 = 10.50. The end.

Hell, I can't understand why you make it such a complicated issue?? Use Proportions to start with. 80 : 8.82 :: 100 : X Multiply the ends by the means and you get 882/80 = $11.025 which includes 5% sales Tax. Sales Tax of 5% is 105/100 = 1.05 Therefore divide $11.025 / 105 = $10.50. Now, how easy was that?? Now I'm 73 and haven't done maths since leaving school!

I got like 10.06 or something....

The answer is the price is $8.82 because stores often never intend to charge an "original price" but rather build room for sales and tax into their prices.

$10.50

8.38

Greetings. The original base cost of the shirt is $10.48 or $11.00 if the taxes are to be considered. Now, since the final price including the taxes is $8.82, We will remove the 5% sales tax from the final cost to get $8.82 times 5% =$0.44. With the sales tax of $0.44 removed, the cost without the tax is $8.38. Now we are told that this price represents 80% of the original cost. Therefore, if we assume that the original cost is X, then 80% of X = $8.38. That is 80X = $838.00, and X= $838/80= $10.48 rounded without the taxes. If the taxes are considered, the tax amount is calculated on $10.48 at 5% for $0.52

He literally just has a channel to talk. This isn't your diary. This isn't a podcast. Do the problem and end it. Mr. J is 10000× better ugh

10 mins and still not solving? Like bruhhhhhh

The teacher uses most of his time in advertising his channel. It is boring.

Why do you have to talk so much in the begin of your videos ?

You take waaaaay toooooo long to get to the point.

Ok just a thought, and having never been taught any "Higher Maths" back in School, one of the things I at least thought I learned was Tax Calculation. So this should have been a straight forward problem, and in this example one of the largest reasons why I never got any traction / sync with it. Why must Math be that complicated when it should be simple. Any way I did this with just simple Multiplication, and came out to $10.55. My question dear Teacher is am I over paying, or are you cheating the Tax Man? Here goes: Take the base price of $8.82, and remove the 5% tax (0.44¢), and get the Base Price of $8.38. Then multiply that by 20% to find the MSRP which was IIRC $1.67 = 10.05. At this point The States going to need their cut so $10.05 x .05 is 50¢ e.g. I get $10.55. I would love to hear back from you on why I'm wrong. I still think this is a total over complication, of what could have been a simpler problem.

ugghhhhhhhhhhh 😴

Talks 2 much

too much talk!

10.14 check yourmath

Get to the point dawg.

Talks too much!
