Solve the problem.In economics, functions that involve revenue, cost and profit are used. Suppose R(x) and C(x) denote the total revenue and the total cost, respectively, of producing a new high-tech widget. The difference 
represents the total profit for producing x widgets. Given R(x) = 60x - 0.4 x2 and 
find the equation for P(x).
A. P(x) = -0.4 x2 + 63x + 13 B. P(x) = 3x + 13 C. P(x) = -0.4 x2 + 57x - 13 D. P(x) = 60x - 0.4 x2
