Valu-Com Electronics manufactures five different models of telecommunications interface cards for personal and laptop computers. As summarized in the following table, each of these devices requires different amounts of printed circuit (PC) boards, resistors, memory chips, and assembly.

	HyperLink	FastLink	SpeedLink	MicroLink	EtherLink
PC Board (Square Inches)	20	15	10	8	5
Resistors	28	24	18	12	16
Memory Chips	8	8	4	4	6
Assembly Labor (in hours)	0.75	0.6	0.5	0.65	1

The unit wholesale and manufacturing cost for each model is as follows.

	HyperLink	FastLink	SpeedLink	MicroLink	EtherLink
Wholesale Price	$189	$149	$129	$169	$139
Manufacturing Cost	$136	$101	$96	$137	$101

In their next production period, Valu-Com has 90,000 square inches of the PC board, 100,000 resistors, 30,000 memory chips, and 5000 hours of assembly time available. They can sell all the products they can manufacture, but the marketing department wants to be sure they produce at least 500 units of each product and at least twice as many Fast Link cards as HyperLink cards. Formulate an LP model to maximize the profit. I suggest you write down the complete formulation, including decision variables, objective function, and constraints first before you answer the multiple-choice questions.

Given the following decision variables:

X1: Number of Hyperlinks to produce

X2: Number of FastLinks to produce

X3: Number of SpeedLinks to produce

X4: Number of MicroLinks to produce

X5: Number of EtherLinks to produce

What is the objective function?
