Question 925758
Rory has $10 consisting of quarters, dimes, and nickels. If she has 10 more dimes than quarters and twice as many nickels as quarters, how many of each coin does she have?
***
let x=number of quarters
x+10=number of dimes
2x=number of nickels
..
.25x+.10(x+10)+.05*2x=10.00
.25x+.10x+1.00+.10x=10
.45x=9
x=20
x+10=30
2x=40
number of quarters=20
number of dimes=30
number of nickels=40
