Answer: 80 quarters
55 nickels
Explanation:
Equation 1
q + n = 135
q = 135 - n
Also we know the dollar values: 0.25q + 0.05n = 22.75 ,call this equation 2
Substituting in equation 2, we get
0.25 (135-n) + 0.05n = 22.75
33.75 - 0.25n + 0 05n = 22.75
-0.25n + 0.05n = 22.75 - 33.75
-0.20n = -11
n = 11/0.20 = 55 = nickels
If q + n = 135
q = 135 - 55 = 80 = quarters
