In Figure 13-2, which of the graphs represents a firm that is a sales revenue maximizer?

Usharani consumes 35 apples a week and 14 loaves of bread. Apples cost $1 each and bread costs $2 per loaf. Usharani is maximizing his utility and finds that the marginal utility from his 35th apple

A) equals his marginal utility from his 14th loaf of bread. B) is twice his marginal utility from his 14th loaf of bread. C) is half his marginal utility from his 14th loaf of bread. D) is such that his total utility from apples equals his total utility from bread.

Even though a perfect price discriminator can extract all of the consumer surplus, how can it be efficient?

What will be an ideal response?
