Part 1 Define and graph the price elasticity of demand
1. (Calculating Price Elasticity of Demand) Suppose that 50 units of a good are demanded at a price of $1 per unit. A reduction in price to $0.20 results in an increase in quantity demanded to 70 units. Show that these data yield a price elasticity of 0.25. By what percentage would a 10 percent rise in the price reduce the quantity demanded, assuming price elasticity remains constant along the demand curve?
2. (Price Elasticity and Total Revenue) Fill in the blanks for each price: quantity combination listed in the following table. Now graph this relationship, making sure to label each axis. What relationship have you depicted?
