Calculate the arc cross-elasticity

Reference no: EM13175667

Assume that demand for product A can be expressed as QA = 500 - PA + 3PB and demand for product B can be expressed as QB = 300 - 2PB + PA. Currently, market prices and quantities for these products are PA = 5, PB= 2, QA = 481, and QB = 301.

a. Suppose the price of product B increases to 3. What happens to quantity demanded of both products?

b. Calculate the arc cross-elasticity between product A and product B using prices for product B of 2 and 3.

c. Are these goods substitutes or complements?
