The price-demand and cost functions for the production of microwaves are given asp= 195 - q/40and C(g)C(q) = 19000 + 30q,where Q is the number of microwaves that can be sold at a price of p dollars per unit and C(q) is the total cost (in dollars) of producing Q units.(D) Evaluate the marginal revenue function at q = 1000.R'(1000) =(E) Find the profit function in terms of q.P(q)=(F) Evaluate the marginal profit function at q = 1000.P'(1000)
