b. an increase in the minimum wage would decrease the total incomes of teenage workers as a group.

c. the unemployment effect of an increase in the minimum wage would be relatively large.

d. the cross elasticity of demand between teenage and adult workers is positive and very large.

a. an increase in the minimum wage would increase the total incomes of teenage workers as a group.

d. price of X/percentage change in quantity demanded of Y.

c. quantity demanded of X/percentage change in price of Y.
