please help please

The scarves take 2 hours of labor to produce, and the sweaters take 14 hours. The labor available is limited to 40 hours per week, and the total production capacity is 5 items per week. Write a system of inequalities representing this situation, where x is the number of scarves and y is the number of sweaters. Then graph the system of inequalities

**Miley**, Thursday, January 31, 2008 at 4:48pmMake scarves =x and sweaters = y.

2x + 14y <(or equal to) 40.

I think that's one of the constraints but I'm not sure how to get the other one.

I don't think my answer is right though!

**drwls**, Thursday, January 31, 2008 at 4:58pm2x + 14y </= 40

You can also write that as

x + 7y </= 20

x + y <= 5

Draw both of these straight lines:

y = 20/7 - x/7

y = 5-x

Then find the region of the graph that lies below BOTH lines, AND for which both x and y are zero or positive. It is a quadrilateral with a right-angle corner at the origin. We cannot draw graphs for you here.
