Individual problems: 4-2 The marginal revenue of the running shoes is less than the marginal benefit [$55<$60]. For the tennis shoes, the marginal revenue is greater than the marginal benefit [$55>$45]. Thus, the shoe company should sell the tennis shoes to the Chinese retailer, but refuse to sell the running shoes at that price. 4-4 This is an extent decision, so we have to measure the marginal benefit of adding a copier and the marginal benefit of adding a worker. The marginal productivity of a copier is 50,000 pages per day (100,000 pages/2 copiers). The marginal productivity of a worker is 10,000 pages per day (50,000 pages/5 workers). An extra copier will add five times much as an extra worker, but will cost less than five times as much. Buy a copier.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
