Question

Michael has $1.95 totally in his collection, consisting of quarters and nickels. The number of nickels is three more than the number of quarters. how many quarters and nickels does Michael have?

Answer 1

1 nickel=$0.05
1 quarter=$0.25
let the number of quarters be x, the number of nickels will be 3+x
thus:
0.05(3+x)+0.25x=1.95
0.05x+0.15+0.25x=1.95
0.30x=1.8
x=6
thus the number of quarters is 6
the number of nickels=6+3=9
