How much should the firm charge for the new and complementary products to obtain 30% profit margin. Assume it costs $300 and $200 to make the new and complementary products, respectively. The firm would like to start its own fleet to transport products from the warehouses to the customers. If each truck can fit 15 products in total (complementary+new), how many trucks should the firm purchase to be used at each warehouse? (Assume that trucks will not travel between warehouses only from the warehouses to the customers.)
