Andrew has a limited weekly income of $65, and he spends it all on cheeseburgers and
Good J. Assume the price of each cheeseburger is $10 and the price of Good J is $5
per unit.
(a) Calculate Andrew's consumer surplus from the second unit of Good J. Show your
work.
(b) Identify the quantity of cheeseburgers and the quantity of Good J that will
maximize Andrew's total benefit given his weekly income. Explain using marginal
analysis.
(c) If Andrew's weekly income increases from $65 to $75, would Andrew be able to buy
5 cheeseburgers and 6 units of Good J? Explain using numbers.
(d) Suppose the price of Good J decreases by 10% and Andrew buys 12% more of
Good J and 8% more of Good S. Based on this change, identify whether Good J and
Good S are substitutes, complements, or not related. Explain using numbers.
(e) Suppose instead that cheeseburgers are produced in a perfectly competitive
market and the price of beef, an input to the production of cheeseburgers, decreases. If
cheeseburgers are a normal good, will the quantity of cheeseburgers that will
maximize Andrew's total benefit increase, decrease, or stay the same? Explain.
