Suppose the demand curve for a product is given by Q = 10 − 2P + PS, where P is the price of the product and PS is the price of a substitute good. The price of the substitute good is $2.00. (1)Suppose P = $1.00. What is the price elasticity of demand? What is the cross-price elasticity of demand? (2)Suppose the price of the good, P, goes to $2.00. Now what is the price elasticity of demand? What is the cross-price elasticity of demand?
