Mr. Alvarado bought a total of 20 pounds of grass seed at the nursery for $168. He paid $9 per pound for Kentucky blue grass and $6 per pound for Tall Fescue. Which system of equations can be used to find the amount X (in pounds) of Kentucky blue grass and the amounty (in pounds) of Tall Fescue Mr. Alvarado purchased?
X+ y = 168
9x + y = 20
Ox+y = 20
6x + 9y = 168
x+y = 20
9x + y = 168
Ox+y=168
6x + 9y = 20
