The following questions are based on this problem and accompanying Excel windows.

 

Jones Furniture Company produces beds and desks for college students. The production process requires carpentry and varnishing. Each bed requires 6 hours of carpentry and 4 hour of varnishing. Each desk requires 4 hours of carpentry and 8 hours of varnishing. There are 36 hours of carpentry time and 40 hours of varnishing time available. Beds generate $30 of profit and desks generate $40 of profit. Demand for desks is limited, so at most 8 will be produced.

 

Let          X1 = Number of Beds to produce

 

                X2 = Number of Desks to produce

 

The LP model for the problem is

 

MAX:	30 X1 + 40 X2
Subject to:	6 X1 + 4 X2 £ 36 (carpentry)
	4 X1 + 8 X2 £ 40 (varnishing)
	X2 £ 8 (demand for desks)

The following questions are based on this problem and accompanying Excel windows.The Byte computer company produces two models of computers, Plain and Fancy. It wants to plan how many computers to produce next month to maximize profits. Producing these computers requires wiring, assembly and inspection time. Each computer produces a certain level of profits but faces only a limited demand. There are also a limited number of wiring, assembly and inspection hours available in each month. The data for this problem is summarized in the following table.

 

Computer Model	Profit per Model ($)	Maximum demand for product	Wiring Hours Required	Assembly Hours Required	Inspection Hours Required
