The price-demand and cost functions for the production of microwaves are given as p=255−x90 and c(x)=9+110x, where x is the number of microwaves that can be sold at a price of p dollars per unit and c(x) is the total cost (in dollars) of producing x units. (a) find the marginal cost as a function of x. c′(x) = equation editorequation editor (b) find the revenue function in terms of x. r(x) = equation editorequation editor (c) find the marginal revenue function in terms of x. r′(x) = equation editorequation editor (d) evaluate the marginal revenue function at x=1500. r′(1500) = equation editorequation editor (e) find the profit function in terms of x. p(x) = equation editorequation editor (f) evaluate the marginal profit function at x=1500. p′(1500) = equation editorequation editor
