#2 – A computer company manufactures two types of computers. Each type of computer will require assembly time, inspection time, and storage space. The amounts of each of these resources that can be devoted to the production of the computers is limited. The manager wants to determine the quantity of each computer to produce to maximize the profit generated by sales of these computers.

In order to develop a suitable model of the problem, the manager has met with design and manufacturing personnel. As a result of those meetings, the manager has obtained the following information:

 Type 1 Type 2 Profit per unit \$60 \$75 Assembly time per unit 4 hours 10 hours Inspection time per unit 30 minutes 20 minutes Storage space per unit 3 cubic feet 3 cubic feet

The manager has also acquired information on the availability of resources. These daily amounts are:

 Resource Amount Available Assembly time 100 hours Inspection time 22 hours Storage space 39 cubic feet

The manager also met with the firm’s marketing manager and learned that demand for the microcomputers was such that whatever combination of these two types of computers is produced, all the output can be sold.

b) What profit do we expect this will result in?

c) What contraints are binding?
