Hi, I just want to ask, what if the S1 has the lowest value, thus, it is the outgoing variable that is replaced by variable x as the incoming variable, how is that? The next table would be change? Since S1 has the lowest value? Or we stick to the step where in S2 is the outgoing variable that will replaced by variable x as the incoming variable? I hope you answer me, I badly needed to know, you're the only one explanation I've Understood easily 😭
@KeshavJadhav2 жыл бұрын
To decide outgoing variable, we need to calculate ratio column= b/key column. I am sure if you once again watch this video till end, then you will clearly understand the steps.

when creating the new row 2 in the final tableau, instead of your formula R2=R2-0.5xR1, i multiplied the old row 2 by 2 and then minused the new row 1. (meaning my values were all double yours). I have not got the same final results and it indicates that s1 variable is still profitable (which is obviously isn't). Is there therefore a correct and incorrect way to formulate new rows? Plzzz help as exam is next week :))))
@KeshavJadhav3 жыл бұрын
Dear Megan Jones, Basically we need to write operation to convert other elements in key column onto zero (0.5 in R2). So, correct operation can be R2=R2-0.5R1. In your operation our basic objective behind writing operation is not fulfilled.

He estimates that the total monthly demand of computers will not exceed 250 units. Determine the number of units of each type of computers which the merchant should stock to get maximum profit if he does not want to invest more than Birr 70 lakhs and if his profit on the desktop model is Birr 4500 and on portable model is Birr 5000.
