1.Marginal profit is equal to marginal revenue plus marginal cost.

True or false

Spacely Sprockets' short-run cost curve is C(q,K)=25q2K+15KC(q,K)=25q2K+15K, where q is the number of Sprockets produced and K is the number of robot hours Spacely hires. Currently, Spacely 2.hires 10 robot hours per period. The short-run marginal cost curve is MC(q,K)=50qKMC(q,K)=50qK. If Spacely receives $250 for every sprocket he produces, his profit maximizing output level is 50.

True or False

3.Consider a competitive market in which the market demand for the product is expressed as P = 75 - 1.5Q, and the supply of the product is expressed as P = 25 + 0.5Q. Price, P, is in dollars per unit sold, and Q represents the rate of production and sales in hundreds of units per day. The typical firm in this market has a marginal cost of MC=2.5+10qMC=2.5+10q.

In this case, the typical firm will maximize its profit at the point where MC = P =
