A coin bank has twice as many nickels as dimes and five times as many pennies as dimes. The value of collection is 2$ how many pennies buckles and dimes are in the collection?
let x=number of dimes in the coin bank
2x==number of nickels in the coin bank
5x=number of pennies.10x+.05 in the coin bank
.10x+.05*2x+.01*5x=2.00
.25x=2.00
x=8
2x=16
5x=40
number of dimes in the coin bank= 8
number of nickels in the coin bank=16
number of pennies. in the coin bank=40
