there are a total of 38 coins. The total value of the coins is $3.70. There are twice as many dimes as quarters. find the number of nickles, dimes and quarters in the meter
***
let x=number of quarters
2x=number or dimes
quarters+dimes+nickels=38
number of nickels=38-(quarters+dimes)=38-3x
..
.25x+.10(2x)+.05(38-3x)=3.70
.25x+.20x+1.9-.15x=3.70
.30x=1.8
x=6
2x=12
38-3x=20
number of quarters=6
number or dimes=12
number of nickels=20
