2. Valu-Com Electronics manufactures two different models of telecommunication interface cards for personal computers. As summarized in the following table, each device requires different amounts of PC board, resistors, memory chips, and assembly.

	Per unit requirement
	HyperLink	FastLink
PC Board (square inches)	20	15
Resistors	28	24
Memory chips	8	8
Assembly labor (in hrs)	0.75	0.6

The wholesale price and the manufacturing cost for each model are as follows:

	Per unit revenue/cost
	HyperLink	FastLink
Wholesale Price	$189	$149
Manufacturing Cost	$136	$101

In their next production period, Valu-Com has 80,000 square inches of PC board, 100,000 resistors, 30,000 memory chips, and 5,000 hours of assembly time available. The company can sell all the products it can manufacture, but the marketing department wants to be sure that they produce at least 1,000 units of each product. Valu-Com would like to know how many of each product to produce in order to maximize the total profit.

Please formulate an LP model for this problem.
