This topic is locked. If you want to discuss this question please re-post it in the respective forum.

The selling price for q units of a product is given by the equation p = 250-25q. The cost of producing q units of the product is:

C = 100+50q.

What is the maximum revenue that can be generated? What is the maximum profit that can be generated?

The same principles apply to this question as to the other question you posed regarding maximum revenues with sales.

What is the maximum revenue that can be generated? What is the maximum profit that can be generated?

total sale = SP * sold qty
= (250-25q)*q
=250q -25q^2

it'll be max when first derivative is zero
250 - 50q = 0
q = 5

max revenue = (250-125)*5 = 625

Profit = revenue - cost
=(250-25q - 100-50q)*q
=150q - 75q^2

max profit when first derivative is zero, 150 - 150q = 0, q = 1
Max profit = 150 - 75 = 75

Could you tell us the source of these questions. I doubt that these are GMAT questions.
