Question 1091101: 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 5 pound 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. How much of each grass is used?
I don't understand how to solve this at all. How do I figure out how much k is if I don't know how much Tall Fescue is in the mixture?
Extra note: there is a table that needs to be filled too. This is basically what it looks like.
