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?
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
