You can put this solution on YOUR website! Sally has three times as many dimes as nickels and twice as
many quarters as dimes. In all she has $5.55. How many coins of
each type does she have?
let x=number of nickels
3x=number of dimes
2*3x=6x=number of quarters
.05x+.10*3x+.25*6x=5.55
.35x+1.50x=5.55
1.85x=5.55
x=3
3x=9
6x=18
number of nickels=3
number of dimes=9
number of quarters=18
