Javon is consuming his optimal utility-maximizing consumption bundle of lobster and
macaroni-and-cheese dinners. Call this bundle A. His income is $100, the price of a
macaroni-and-cheese dinner is $5, and the price of a lobster is $20. Put lobsters on the
vertical axis and put macaroni-and-cheese dinners on the horizontal axis. His income
increases to $500 and the prices of macaroni-and-cheese dinners and lobster remain
constant. With the increase in income, Javon changes his consumption of the two goods
and now maximizes utility at bundle B. If macaroni-and-cheese dinners are an inferior
good for Javon:
A) at bundle B, Javon consumes more macaroni-and-cheese dinners.
B) at bundle B, Javon consumes less lobster.
C) at bundle A and bundle B, the marginal utility of lobster is 5.
D) at bundle B, Javon consumes more lobster.
