Math Problem Statement
A manufacturer of tennis rackets finds that the total cost of manufacturing x rackets/day is given by 0.0001x2 + 4x + 500 dollars. Each racket can be sold at a price of p dollars, where p = −0.0004x + 9. Find an expression giving the daily profit P for the manufacturer, assuming that all the rackets manufactured can be sold. Hint: The total revenue is given by the total number of rackets sold multiplied by the price of each racket. The profit is given by revenue minus cost. (Simplify your answer completely.)
