	A.	no change
	B.	a decrease of $18000

Consider an LP model of a manufacturing process concerned with the production of four variants of the same product, A,B,C , and D, each of which will yield a certain profit per unit sold, and each requires a certain time for assembly, packing and polishing. Given the current state of the labor force the company estimates time limits available for each of the availability operation. The objective is to determine how many of each variant to make to achieve the greatest possible profit while satisfying all constraints. Figure A.
