Chapter 4 review quiz
1) The price elasticity of demand measures:

c) the percentage change in quantity demanded as a result of a 1 percent change in price
d) the slope of the demand curve
2) If a 1 percent fall in the price of a commodity causes the quantity demanded of the commodity
to increase 2 percent, demand is:
