Gao's restaurant produces tacos using workers. The table below shows how many tacos can be served per hour with
different quantities of workers. What is the marginal product and average product of labor for her restaurant?
To answer this question, fill in the marginal product of labor and the average product of labor in the table below. (Enter
numeric responses using real numbers rounded to two decimal places.)

Suppose that after hu
icane Irene, the average income in Cape Charles, Virginia decreased by percent. In response to
this change in income, suppose the quantity of steak demanded in Cape Charles (holding the price of steak constant)
decreased by percent. What is the income elasticity of demand for steak in Cape Charles?

The income elasticity of demand for steak in Cape Charles is . (Enter your response rounded to two
decimal places.)
In this instance, steak in Cape Charles is (1) .
Suppose that the price elasticity of demand for iPhone is -2.70, cross-price elasticity of demand between iPhones and iPads
is -0.90, and income elasticity of demand of iPhone is 1.95. How do you interpret each of those numbers? Explain what
each of those numbers mean about the iPhones and iPads.
5. On chapter 7, we learned the concepts of utility maximization. Based on your understanding from the chapter, explain where
a demand curve comes from. In other words, how do we use utility maximization principle to create a demand curve?
Explain the steps.[Hint: explain the process by which we created the demand curve on the grapes
anana example we did
in class]
