1. Production Turley Tailor Inc. makes long-sleeve, short sleeve,and sleeveless blouses. A long-sleeve blouse requires 1.5 hours of cutting and 1.2 hours of sewing. A short-sleeve blouse requires 1 hour of cutting and .9 hour of sewing. A sleeveless blouse requires .5 hour of cutting and .6 hour of sewing. There are 380 hours of labor available in the cutting department each day and 330 hours in the sewing department. If the plant is to run at full capacity,how many of each type of blouse should be made each day?

2. Solve by Gauss-Jordan method.

x+3y- 6z =7
2x- y+2z = 0
x+y+2z = -1

3. Solve by Gauss Jordan method.

4x - 3y + z + w = 21
-2x -y + 2z + 7w = 2
10x- 5z- 20w = 15
