Assume that the company in Problem 3.16 receives $800 for each item sold,

(a) Express the company’s profit π as a function of the number x of items sold and evaluate the function at

(b) x – 25 and

(c) x = 40.

For earlier practical applications that could have also been expressed as functions, see Problems 2.21 to 2.34.

(a) With total revenue, R(x) = 800x, the profit function is (b) (x) = R(x)-C(x) 7(x) = 800x [450x + 8250] = 350x-8250- (25) 350(25) - 8250 = 500 (c) (40) - = 350(40) 8250 = 5750
