Answer:
If the marginal cost of a gallon of milk increases, how will the household respond?
C. The household will continue to consume the same amount.
Explanation:
The increase in the marginal cost of a gallon of milk will not greatly alter the quantity of milk consumed by a typical household. At this initial point when the marginal cost of a gallon of milk increases, the household is not affected because the seller has not shifted the cost to consumers. Even when the marginal cost increase is shifted to the consumers, the quantity required by the household remains the same. What may likely change at that stage is that the price at which the a household buys a gallon of milk increases marginally. The marginal increase will not distort demand for milk but households can change brands and not the quantity of milk, or at worst, they pay a higher price for a gallon.
