Chapter 7.3, Problem 35E
Manufacturing Two departments, A and B, of a firm need differing amounts of steel, wood, and plastic. The following table gives the amounts of the products needed by the departments.
These three products are supplied by two suppliers, DeTuris and Marriott, with the unit prices (in dollars) given in the following table.
| DeTuris | Marriott | |
| Steel | 600 | 560 |
| Wood | 300 | 200 |
| Plastic | 300 | 400 |
- a. Use matrix multiplication to determine how much these orders will cost each department at each of the two suppliers.
- b. From which supplier should each department make its purchase?
