Ari is currently consuming 10 hot dogs and 8 hamburgers per week. The last hot dog she consumed yielded 20 utils while the last hamburger she ate gave her 25 utils. If hot dogs cost $2 and hamburgers cost $2.50, is Ari consuming the correct quantities of these two goods to be in consumer equilibrium?

Yes, there is no need to change the eatings habits

Explanation:

Ari will maximize utility until

MU / P for both is equal in order to be at equilibrium

So, in this case,

For Hot dogs

= MU / P

where

MU is marginal utils, which is 20

P is Price, which is $2

So,

= 20 / $2

= 10

For Hamburgers

= MU / P

where

MU is marginal utils, which is 25

P is Price, which is $2.5

So,

= 25 / $2.5

= 10

Therefore, MU / P for hot dog = MU / P for Hamburger

Hence, there is not need to change the eatings habits.
