TRUCKING. Bay City Movers is a local company that specializes in intercity moves. In the business plan submitted to its backers, Bay City has committed itself to a total trucking capacity of at least 42 tons.

 The company is in the process of replacing its entire fleet of trucks with 1 -ton pickup trucks and 2 j-ton  moving van-type trucks. The 1-ton pickup trucks will be manned by one worker, whereas the large vans will utilize a total of four workers for larger moves. Bay City Movers currently employs 63 workers and has facilities for at most 50 trucks. Pickup trucks cost the company $24,000 each; the moving vans cost $60,000 each. The company wishes to make a minimum investment of capital that will provide a trucking capacity of at least 42 tons while not requiring any additional workers or trucking facilities.
