wo profit-maximizing ice-cream vendors are located at opposite ends of a boardwalk along a 5-mile stretch of beach. Vendors A and B initially sell ice-cream cones for $3.00. There are 500 consumers uniformly distributed along the boardwalk. Suppose that a consumer incurs $0.05 per 1/2 mile in travel costs and that the vendor's marginal cost is $1.00.
