The price-demand and cost functions for the production of microwaves are given as p= 105 - q/90 and C(q) = 22000 + 90q,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.(A) Find the marginal cost as a function of q.C'(q) =(B) Find the revenue function in terms of q.R(g) =(C) Find the marginal revenue function in terms of q.R'(q) =(D) Evaluate the marginal revenue function at g = 1000.R'(1000) :
