1. Fundamentals of consumer choice Suppose that a glass of acai berry juice at Beth's gym cafeteria costs as much as a can of soda. Beth knows that while acai berry juice improves health by providing important vitamins, soda drinks contain artificial ingredients and too much sugar, which causes diabetes. Beth is thirsty and buys herself a glass of juice. How might economic theory explain Beth's choice

The correct answer is letter "D": As juice and soda cost the same, Ana buys the drink that she expects will yield her the greatest benefit.

Explanation:

Consumer equilibrium refers to the point where consumer gains maximum satisfaction from consuming a determined number of goods or services which makes the consumer reluctant to change his or her consumption pattern. For this to be possible, the products consumed by individuals must provide a higher yield than the forgone products. Usually, there no other factors influencing consumers' decisions implying the price levels of those products are the same.
