Question 1134434
Given function of average profit to be A(x) = 36-8400/x

x represents the number of purses:
The question asks us to solve for x when the average profit is given to be $20.

Substitute A(x) = 20:

20 = 36-8400/x
20-36 = -8400/x
-16 = -8400/x
x = -8400/-16
x = 525

Solution: 525 purses must be sold so that the average profit = $20
