A. lower than B. equal to C. higher than D. not comparable to 11. Assume the demand function for skin care products is given by Q = 1,000 – 20 P + 5I. If P=\$25 and I=\$1,000 currently, then: A. skin care products are a normal good. B. the elasticity of demand is equal to 11. C. skin care products are inferior. D. The price is too high 12. If the demand for product A displays high and positive cross-price elasticity with respect to the price of product B, then: A. the demand for product A is likely to have a low price elasticity. B. products A and B are substitutes. C.…show more content…
