Find the marginal profit function Find MP(50), then interpret the meaning of MP(50) in the context of the problem

1) Let the price-demand function in dollars per Item be p(x) = x - 12x + 40 and the cost function be C(x) = 62x2 + 27500, where C(x) is measured in dollars from the production and sales of x items. a) Find the profit function P(x). Simplify
