1. RVW (Restored Volkswagens) buys 15 used VW's at each of two car auctions each week held at different locations. It then transports the cars to repair shops it contracts with. When they are restored to RVW's specifications, RVW sells 10 each to three different used car lots. There are various costs associated with the average purchase and transportation prices from each auction to each repair shop. Also, there are transportation costs from the repair shops to the used car lots. RVW is concerned with minimizing its total cost given the costs in the table below.

I need answer C

1. Given the costs below, draw a network representation for this problem.

Repair Shops				Used Car Lots
	S1	S2		L1	L2	L3
Auction 1	550	500	S1	250	300	500
Auction 2	600	450	S2	350	650	450

2. Formulate this problem as a transshipment linear programming model.
3. Solve the problem using the computer (MS Excel).
