What happens to consumer surplus in the cell phone market if cell phones are normal goods and buyers of cell phones experience an increase in income? a. Consumer surplus decreases. b. Consumer surplus remains unchanged. c. Consumer surplus increases. d. Consumer surplus may increase, decrease, or remain unchanged.

D

Explanation:

Normal goods are goods that are goods whose demand increases when income increases and falls when income falls

Consumer surplus is the difference between the willingness to pay of a consumer and the price of the good.

Consumer surplus = willingness to pay – price of the good

If consumers income increases, their demand for cell phone would increase. This would lead to an increase in price of the good.

Also, willingness to pay would ncrease as a result of income increase

If increase in willingess to pay exceeds increase in price, consumer surplus increases, if not it reduces. If the increase is the same, it remains the same
