Question

A manufacture has been selling 1050 television sets a week at 360 dollars each. A market survey indicates that for each 20 -dollar rebate offered to a buyer, the number of sets sold will increase by 200 per week.

p(x)=1x/10 + 465

How large of a rebate should the company offer to a buyer, in order to maximize its revenue?

I did 697.5-360=337.5. Is this right?
