Korea’s production possibilities frontier would be 0.33.
c. the slope of Japan’s production possibilities frontier would be 0.2 and the slope of

Suppose a tax is imposed on each new hearing aid that is sold. The supply curve is a
typical upwardsloping straight line, and the demand curve is a typical downwardsloping
straight line. As a result of the tax, the equilibrium quantity of hearing aids decreases
