Question: The price-demand equation and the cost function for the production of table saws are given, respectively, by x = 8400 – 36p and C(x) = 60000 + 72x, where x is the number of saws that can be sold a price of $p per saw and C(x) is the total cost (in dollars) of producing a saw.

(A) Express the price p as a function of the demand x.

(B) Find the marginal cost.

(C) Find the revenue function, marginal revenue, profit function, and marginal profit.
