In economics, functions that involve revenue, cost, and profit are used. For example, suppose that R(x) and C(x) denote the total revenue and the total cost, respectively, of producing a new kind of tool for King Hardware Wholesalers. Then the difference P(x) = R(x) - C(x) represents the total profit for producing x tools. Given R (x) = 60x - 0.4x2 and C(x) = 3x + 13, find each of the following.
(a) P(x)
(b) R(100), C(100), and P(100)
