Angela Cruz · Answer 1

b. Falls from a positive amount to another positive amount.

Explanation:

The relevant economics analysis here is indifference analysis in which a combination of two goods will give the same level of utility to the consumer which makes the consumer to be indifferent.

In the question, the person is indifferent between consuming Diet Coke (DC) and Diet Pepsi (DP) since he will derive the same of satisfaction from either of the two.

Since P_DC < P_DP, consumer will consume more of DC. If P_DC rises but it remains less than P_DP, the consumption of DC will fall from a positive amount to another positive amount, because his level of income is assumed to be constant but he can still buy quantity of DC that is higher, though lower than the quantity he could buy before, than quantity of DP at the same constant level of income.

I wish you the best.
