In year 1 the average price of X is $10, and in year 2 the average price of X is $23. If consumers buy more units of X in year 2 than in year 1, it follows that a. the law of supply does not hold for good X. b. demand for good X could be lower in year 2 than in year 1. c. supply of good X could be less in year 2 than in year 1. d. good X buyers have received an increase in income between year 1 and year 2, and good X is a normal good. e. good X buyers have received a decrease in income between year 1 and year 2, and good X is a normal good.

D

Explanation:

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

If good X is a normal good and the consumers income increases, the demand for good X would increase

It would have been that the Law of demand not supply that didn''t hold

according to the law of supply, the higher the price, the higher the quantity supplied and the lower the price, the lower the quantity supplied.

According to the law of demand, the higher the price, the lower the quantity demanded and the lower the price, the higher the quantity demanded.
