28) mr. chan has an income of $20 that he is spending on donuts and cheese in such
amounts that he derives 25 utils of satisfaction from the donuts and 25 utils of
satisfaction from the cheese. on the basis of this information we:
a.cannot say whether or not chan is buying donuts and cheese in equilibrium amounts.
b.can say that chan should buy more cheese and fewer donuts.
c.can say that chan should buy more donuts and less cheese.
d.can say that chan is buying the utility-maximizing amounts of donuts and cheese.
29) if the law of diminishing returns applies to study time:
a.the 10th hour of study will likely be less productive than the 3rd.
b.this implies that longer lectures are less productive than shorter ones.
c.there is no benefit to studying a subject more than 5 hours in any given day.
d.people with less intelligence necessarily experience diminishing returns sooner than

A.any number of workers can be hired at the going equilibrium wage rate.
B.the firm must lower product price to increase its sales.
C.the higher wage needed to attract additional workers must also be paid to the workers
already employed.
