b.1.50, and an increase in price will result in a decrease in total revenue for good A.
c.0.67, and an increase in price will result in an increase in total revenue for good A.
d.0.67, and an increase in price will result in a decrease in total revenue for good A.

trade involving many countries and many goods.
14) Assume the price of gasoline is $2.40 per gallon, and the equilibrium quantity of
gasoline is 12 million gallons per day with no tax on gasoline. Starting from this initial
situation, which of the following scenarios would result in the largest deadweight loss?

demanded by 2 percent and it increases the quantity of gasoline supplied by 5 percent;
and the tax on gasoline amounts to $0.40 per gallon.
b.A 10 percent increase in the price of gasoline reduces the quantity of gasoline
demanded by 2 percent and it increases the quantity of gasoline supplied by 7 percent;
and the tax on gasoline amounts to $0.40 per gallon.
c.A 10 percent increase in the price of gasoline reduces the quantity of gasoline
demanded by 1 percent and it increases the quantity of gasoline supplied by 8 percent;
and the tax on gasoline amounts to $0.35 per gallon.
