A bakery works out a demand function for its chocolate chip cookies and finds it to be q = D(x) = 692-13x, 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? ○ A. Less than 27¢ O B. Greater than 27¢ OC. Prices cannot be elastic in this case OD. Prices are elastic at all values. d) At what prices is the elasticity of demand inelastic? O A. Greater than 27¢ OB. Prices cannot be inelastic in this case OC. Less than 27¢ OD. Prices are inelastic at all values 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.) f) At a price of 13¢ per cookie, will a small increase in price cause the total revenue to increase or decrease? ○ Decrease Increase
