-------
Value Equation::: 25q + 10d + 5n + p = 2152 cents
Quantity Eq::::: p = 3n
Quantity Eq::: q = n + 13
Quantity Eq::: n = d - 58
-------
Substitute and solve:
25(n+13) + 10(n+58) + 5n + 3n = 2152
-------
43n+ 905 = 2152
43n = 1247
n = 29 (# of nickels)
p = 3n = 87 (# of pennies)
q = n + 13 = 42 (# of quarters
d = n+58 = 87 (# of dimes)
