3. The production function for Marty’s Frozen Yogurt is given in Problem 1. The costs are given in Problem 2.

a. For each of the given levels of output, calculate the average fixed cost (AFC), average variable cost (AVC), and average total cost (ATC) per cup of frozen yogurt.

b. On one diagram, draw the AFC, AVC, and ATC curves.

c. What principle explains why the AFC declines as output increases? What principle explains why the AVC increases as output increases? Explain your answers.

d. How many cups of frozen yogurt are produced when average total cost is minimized?
