a)28
b)24
c)4
d)12

d)total utility is maximized
e)None of the above.

8)As more hours of Internet access are purchased, everything else equal, marginal utility will tend to

b)decrease, but at different rates for different people
c)decrease at different rates for different people, but at the same rate as for other goods
d)increase at the same rate for all consumers
e)increase, but at a decreasing rate for all consumers

9)A consumer who follows the principle of utility maximization subject to constraints will

a)consume at a point on her budget line
b)consume each good until its marginal utility is zero
c)adjust her consumption pattern so that the marginal utilities of all goods are equal
d)consume more of a good only if its price rises
e)stop consuming any good whose price rises

10)If bread costs $1 per pound and meat costs $4 per pound, a consumer whose marginal utility of meat equals 80 utils per pound is maximizing utility only if the marginal utility per pound of bread equals

a)4 utils
b)5 utils
c)10 utils
d)20 utils
e)80 utils

11)Ignoring all other goods, if Cathy's marginal utility per dollar for bread is 10 utils per dollar and for cheese it is 30 utils per dollar, her

a)total utility could be increased by buying more bread and less cheese
b)total utility could be increased by buying more cheese and less bread
c)total utility would be maximized if the price per pound of cheese is one-third the price per pound of bread
d)marginal utility would be maximized if the price per pound of cheese is one-third the price per pound of bread
e)none of the above
