If Debi has $2.80 in a collection of dimes and nickels. The number of nickels is five more that the number of dimes. Find the number of each type of coin.
**
let x=number of dimes
x+5=number of nickels
.10x+.05(x+5)=2.80
.10x+.05x+.25=2.80
.15x=2.55
x=2.55/.15=17
x+5=22
..
number of dimes=17
number of nickels=22
