Suppose college graduates earn $25 an hour and high school graduates earn $5 an hour. Suppose too that the marginal product of college graduates at Johnson Tools is 8 hammers per hour, while the marginal product of high school graduates is 4 hammers per hour (regardless of the number of each type of worker employed). a. What is the least-cost production method for producing 100 hammers in an eight-hour day? O Hire one-third college graduates and two-thirds high school graduates. O Hire two-thirds college graduates and one-third high school graduates. Hire only high school graduates. O Hire half college graduates and half high school graduates. O Hire only college graduates. b. What if the marginal product of high school graduates was instead 2?
