Answer:
Explanation:
We got two equations.
First modeling the total money using x for nickels and y for quarters.
0.05x + 0.25y = $8.80
Our second equation is modeling the total coins.
x + y = 68
Which we can change to substitute for x.
x = 68 - y
Substitute for x to find the answer.
0.05(68 - y) + 0.25y = 8.80
3.4 - 0.05y + 0.25y = 8.80
3.4 + 0.20y = 8.80
0.20y = 5.4
y = 27.
So, there is 27 quarters and 41 nickels.
