Answer:
The marginal cost of second-pint strawberries is $3.
Step-by-step 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
