A) 3 pita wraps and 3 bubble teas
B) 3 pita wraps and 4 bubble teas
C) 4 pita wraps and 2 bubble teas
D) 5 pita wraps and 0 bubble teas
22) Refer to Table 10-1. If Keegan can drink all the bubble tea he wants for free, how many glasses will he consume?

C) 6 glasses
D) 7 glasses
23) Carolyn spends her income on popular magazines and music CDs. If the price of a CD is four times the price of a magazine and if Carolyn is maximizing her utility, she buys
A) both goods until the marginal utility of the last CD purchased is four times the marginal utility of the last magazine purchased.
B) both goods until the marginal utility of the last magazine purchased is four times the marginal utility of the last CD purchased.
C) four times as much magazines as CDs.
D) four times as much CDs as magazines.
24) Suppose Joe is maximizing total utility within his budget constraint. If the price of the last pair of jeans purchased is $25 and it yields 100 units of extra satisfaction and the price of the last shirt purchased is $20, then, using the rule of equal marginal utility per dollar spent, the extra satisfaction received from the last shirt must be
A) 2,000 units of utility.
B) 500 units of utility.
C) 100 units of utility.
D) 80 units of utility.
25) Avner is maximizing total utility by buying sports magazines and protein supplements. For him to buy more sports magazines,
A) the price of protein supplements has to fall.
B) the price of sports magazines has to fall.
C) the price of sports magazines has to rise.
D) Since Avner is maximizing his utility, nothing can change the consumption of sports magazines.
26) Most people would prefer to drive a luxury car that has all the options, but more people buy less expensive cars even though they could afford the luxury car because
A) car buyers are irrational.
B) the total utility of less expensive cars is greater than that of luxury cars.
C) the marginal utility per dollar spent on the less expensive car is higher than that spent on luxury cars.
D) luxury cars cost a lot more than non-luxury cars.
27) If Valerie purchases ankle socks at $5 and gets 25 units of marginal utility from the last unit, and bandanas at $3 and gets 12 units of marginal utility from the last bandana purchased, she

B) MU/P has increased, and Callum should buy less of this good.
C) MU/P has decreased, and Callum should buy more of this good.
D) MU/P has decreased, and Callum should buy less of this good.
30) If Ewan is consuming his utility maximizing bundle and the price of one good falls, what happens to the marginal utility per dollar spent on this good (MU/P), and what should Ewan do?
A) MU/P has increased, and Ewan should buy more of this good.
B) MU/P has increased, and Ewan should buy less of this good.
