A bakery works out a demand function for its chocolate chip cookies and finds it to be q = D(x) = 886- 12x, where q is the quantity of cookies sold when the price per cookie, in cents, is x. Use this information to answer parts a) through f) a) Find the elasticity. E(x)- b) At what price is the elasticity of demand equal to 1? (Round to the nearest cent as needed ) c) At what prices is the elasticity of demand elastic? O A. Less than 37 O B. Greater than 37 O C. Prices cannot be elastic in this case D. Prices are elastic at all values. d) At what prices is the elasticity of demand inelastic? O A. Less than 37 O B. Prices are inelastic at all values O C. Greater than 37 O D. Prices cannot be inelastic in this case e) At what price is the revenue a maximum? x = & (Round to the nearest cent as needed. Use a comma to separate answers as needed.) () At a price of 14 per cookie, will a small increase in price cause the total revenue to increase or decrease? Increase Decrease
