A manufacture has been selling 1250 television sets a week at $450 each. A market survey indicates
that for each $22 rebate offered to a buyer, the number of sets sold will increase by 220 per week.
a) Find the demand function p(x), where is the number of the television sets sold per week.
p(x)
b) How large rebate should the company offer to a buyer, in order to maximize its revenue?
c) If the weekly cost function is 93750 + 150z, how should it set the size of the rebate to maximize
its profit?
