Suppose there are only two ice cream shops, Bob's Ice Cream and Joe's Ice Cream, in Boston, Mass. These two ice cream shops produce identical ice cream cones. Market demand for ice cream cones in Boston is given by Q = 75 - P, where Q is the quantity of ice cream cones and P is the price. Suppose that total costs for Bob's Ice Cream are given by TCBob = 0.1Q2Bob and total costs for Joe's Ice Cream are given by TCJoe = 5QJoe.
