Let X = the number of each type of coin
quarters = .25X
dimes = .10X
nickels = .05X
added together they equal 4.40
.25X+.10X+.05X=4.40
.4X=4.40
divide both sides by .4 to get the variable X by itself
x=11
check the answer:
.25X+.10X+.05X=4.40
.25(11)+.10(11)+.05(11)=4.40
2.75+1.10+.55=4.40
4.40=4.40
