Question 965560: Cheyenne has a collection of coins that consist of nickels and quarters. The value of these coins is $3.60. If the number of nickels in her collection is 3 times the number of quarters, how many of each coin does she have?
Answer by CubeyThePenguin(3113) About Me  (Show Source):
You can put this solution on YOUR website!
n = number of nickels
q = number of quarters

5n + 25q = 360
n = 3q

Write everything in terms of n.

5(3q) + 25q = 360
40q = 360
q = 9

There are 9 quarters and 27 nickels.
