The price-demand and cost functions for the production of microwaves are given as p = 210 - 30 and C(x) = 40000 + 90x where a is the number of microwaves that can be sold at a price of p dollars per unit and O() is the total cost (in dollars) of producing x units. a. Find the profit function in terms of c. P(x) = Preview b. Evaluate the marginal profit function at x = 1500 microwaves rounded to the nearest cent. P' (1500) = $ per microwave Preview
