Explain your reasoning.

Explain your reasoning. The consumer will purchase 3 apples and 2 oranges because this is where the Mu/per dollar is equal and where the consumer maximizes satisfaction for a total utility of 95. (Maximum utility answer is not good enough.)

Identify each of • the following. 4 apples and 4 oranges because that is where Mu/per dollar is equal. • The combination of apples and oranges the • consumer will now purchase.
