Let C(q) C(q) represent the cost and R(q) R(q) represent the revenue, in dollars, of producing q q items and let C (70)=26 C′(70)=26 and R (70)=24 R′(70)=24. Choose the statement that best matches this situation. Correct! The cost of producing the 71st item exceeds the revenue it will generate, so producing the 71st item will reduce the total profit. The marginal cost is greater than the marginal revenue when 70 items are produced, so total profit is negative when 70 units are produced. The marginal cost is greater than the marginal revenue when 70 items are produced, so profits are maximized when some quantity less than 70 is produced. The marginal cost is greater than the marginal revenue, so the firm cannot make a profit. The revenue from the 71st item exceeds the cost to produce it, so producing the 71st item will increase the total profit. Since C (70)>R (70) C′(70)>R′(70), the cost to produce the next unit exceeds its revenue, and producing that unit will decrease the total profit. The only data in the problem is about the increased cost and revenue for producing the 71st item. There is no information about whether total profits are maximized or whether total profits must be positive or negative. Quiz Score: 23 out of 25 Previous Next Last Attempt Details:

### What students are saying

• 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.
