Answer:
there are 59 nickels, 12 quarters, and 213 dimes
Explanation:
- let n = nickels
- let q = quarters
- let d = dimes
first step:
d = 3 (n + q) = 3n + 3q
d + n + q = 284
0.10d + 0.05n + 0.25q = 27.25
second step:
3n + 3q + n + q = 284
0.10 (3n + 3q) + 0.5n + 0.25q = 27.25
third step:
4n + 4q = 284
0.3n + 0.3q + 0.05n + 0.25q = 27.25
fourth step:
n + q = 71
0.35n + 0.55q = 27.25
fifth step:
replace q = 71 - n
0.35n + 0.55(71 - n) = 27.25
sixth step:
0.35n + 39.05 - 0.55n = 27.25
seventh step:
11.8 = 0.2n
eighth step:
n = 59
q = 71 - 59 = 12
d = 284 - n - q = 284 - 59 - 12 = 213
