You can put this solution on YOUR website! Stephanie had a pile of dimes and quarters that had a value of $6.75. If there were twice as many dimes as quarters, how y quarters did Stephanie have?
.
Let q = number of quarters
then
2q = number of dimes
.
.25q + .10(2q) = 6.75
25q + 10(2q) = 675
25q + 20q = 675
45q = 675
q = 15 (number of quarters)
