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
575k + 450(5-k) = 525(5)
It solves quite nicely
