For some time, two firms have charged $0.90 per standard unit of crating materials for shipping a particular type of machine tool and each has been selling about 20,000 units per month. Last month, U-Pak-It reduced its price to $0.80 per unit and its volume increased to 25,000 units. During that month, Boxit (the other company) maintained its price at $0.90 but saw its volume decline to 17,000 units.
a. What is the price elasticity of demand facing U-Pak-It?
b. What is Boxit's cross-price elasticity of demand for U-Pak-It price changes?
c. If the price elasticity of demand for Boxit is the same as that for U-Pak-It, what price reduction for Boxit would be required to increase its monthly volume back to 20,000 units per month?
