a. $6
b. $4
c .$3
d. $2

Answer 1

The marginal cost of buying a second gallon of milk is d. $2.

Step-by-step explanation:

The marginal cost of buying a second gallon of milk can be determined by comparing the cost of purchasing one gallon of milk with the cost of purchasing two gallons at the same time. The price of one gallon of milk is $4, but if you buy two gallons together, the price is $6 for both. So, the marginal cost of buying the second gallon would be the difference between the total price of two gallons and the price of one gallon.

Therefore, the marginal cost of buying a second gallon of milk is $6 - $4 = $2.
