Question 915626: One fourth of Sue's coins are quarters and the rest are nickels. If the total value of the coins is $7.20, how many of each type does she have? Answer by JoelSchwartz(130) (Show Source):
You can put this solution on YOUR website! t=toal number of coins
n=number of nickels in the total number of coins
q=number of quarters in the total number of coins
1/4t=q
3/4t=n
.05*3/4t+.25*1/4t=7.2
.0375t+.0625t=7.2
1/10t=7.2
t=72
q=.25*72
q=18
n=3/4*72
54=n
