Step-by-step explanation:

A) N + Q = 130

B) .05N + .25Q = 15.90

Multiplying equation A by -.05 equals

A) -.05N -.05Q = -6.50 then adding this to B)

B) .05N + .25Q = 15.90 Equals

.20Q = 9.40

Quarters = 47

Nickels = 83

.05*83 + .25*47 = 4.15 + 11.75 = 15.90

quester [9]

The solution for the problem is as follows:

((12x + 15y)/228) = 13
x + y =228

x = kentucky bluegrass
<span>y = chewings fescue
</span>
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.
