Le · Answer 1

Mrs. Simpson should buy less bread and more milk.

Explanation:

Besides the nutritional differences between bread and milk, Mrs. Simpson is not buying the utility-maximizing combination of bread and milk.

When she purchases bread, she is paying $1 for 80 utils, that means that the marginal cost of every util is 1.25¢.

When she purchases milk, she is paying $0.80 for 70 utils, that means that the marginal cost of every util is 1.14¢.

So the marginal cost per additional util is lower for milk.
