The solution for the problem is as follows:
((12x + 15y)/228) = 13
x + y =228
x = kentucky bluegrass
y = chewings fescue
By systems of linear equations, the answers would be:
x = 152
y = 76
Therefore, there should be 152 pounds of Kentucky bluegrass to be used and 76 pounds of chewings fescue.
I hope my answer has come to your help. Thank you for posting your question here in Brainly.
