Lord Greystroke uses his limited income to purchase fruits and nuts; he is currently buying 10
pounds of fruits at a price of \$2 per pound and 5 pounds of nuts at a price of \$6 per pound. The
last pound of fruits added 10 units to Lord Greystroke's total utility, while the last pound of nuts
a.
is making the utility-maximizing choice.
b.
should buy more fruits and less nuts because the last pound of fruits cost less than the last
pound of nuts.
c.
should buy more fruits and less nuts because the last dollar spent on fruits added more to
total utility than the last dollar spent on nuts.
d.
should buy more nuts and less fruits because the last pound of nuts added more to total
