Seventeen new bathing suit stores enter the Santa Barbara market, joining the seven that already existed. As a consequence, the demand schedule facing Swim N Style (and all other stores) falls, while the cost schedules remain constant as in Problem 1:

                                       Suits sold

                                       (per hour)           Price

                                                1                 $31.50

                                                2                   28.50

                                                3                   25.50

                                                4                   22.50

                                                5                   19.50

                                                6                   16.50

                                                7                   13.50

                                                8                   10.50

                                                9                     7.50

                                              10                     4.50

b)   What price will it charge, and what will its profit be?

c)   What is the average cost per swimsuit sold?

d)  How many swimsuits are sold in Santa Barbara each hour, and what is the total cost incurred?

e)   From your calculations in Problem 1, identify the sales level at which Swim N Style's average cost would be a minimum. What is this average cost?

f)    Summarize briefly what you have learned from this problem about the efficiency of monopolistic competition
