Homework Help: Math

Posted by Zoey on Monday, April 16, 2007 at 10:40pm.

A nursery sells Kentucky Blue Grass seed for $5.75 per pound and Tall Fescue seed for$4.50 per pound. The nursery sells a mixture of the two kinds of seed for$5.25 per pound. Let k represent the amount of Kentucky Blue Grass seed the nursery uses in 5 pounds of the mixture.

1.Write an equation to represent the problem.

2.How much Kentucky Blue Grass does the nursery use in 5 pounds of the mixture?

3.How much Tall Fescue does the nursery use in 5 pounds of the mixture?

I k represents the amount of Blue Grass, then 5-k must be the amount of T.F. used

so....

575k + 450(5-k) = 525(5)

It solves quite nicely

Thank you
