Answer:
Juan should increase his consumption of candy and decrease his consumption of baseball cards.
Explanation:
Given that
The baseball cards marginal utility is 20
And the candy marginal utility is 10.
Now If the baseball cards price is $10,
and the candy price is $2
So if we divide the marginal utility with the price so it will come 2 for baseball card and 5 for candy so the consumption of the candy should be increased while on the other hand the consumption of the baseball card should be decreased
