You can put this solution on YOUR website! A youth orginization collected nickels and dimes for a charity drive. By the end of day one they collected $37.45. If there were three times as many dimes as nickels, how many of each type of coin was collected?
--------------------
Equations:
Quantity Equation: d = 3n
Value Equation: 5n + 10d = 3745 cents
----------------------------------
Substitute for "d" and solve for "n":
5n + 10(3n) = 3745
35n = 3745
n = 107 (# of nickels)
---
Since d = 3n, d = 321 (# of nickels)
