2) A bookstore has an annual demand for 85,000 copies of a best-selling book. It costs $0.50 to store one copy for one year, and it costs $45 to place an order. Find the optimum number of copies per order.

A) 3912 copies

B) 4722 copies

C) 5532 copies

D) 3521 copies

B) The demand has unit elasticity.

C) Inelastic

D) None of these

12) The demand for boneless chicken breast, in dollars per pound, is given by q = -0.6p + 7, where p represents the price per pound and q represents the average number of pounds purchased per week per customer. Determine the price at which the demand for boneless chicken breast is unit elastic.
