The grocery store is having a sale on strawberries. One pint of strawberries 1 costs $4, two pints will cost $7, and three pints will cost $9. What is the
marginal cost of the second pint of strawberries?

The marginal cost of second-pint strawberries is $3.

Explanation:

The price of one-pint strawberries = $4

The price of two-pint strawberries = $7

The price of three-pint strawberries = $9

Now we have to find the marginal cost of second-pint strawberries. So, to find the marginal cost we have to subtract the total cost of one pint from the total cost of two pints.

Thus, the marginal cost = the price of two-pint strawberries - The price of one-pint strawberries

Marginal cost = 7 – 4 = $3
