You can put this solution on YOUR website! I have eight more quarters than dimes. If the coins are worth $6.20, how many dimes are there?
.
Let d = number of dimes
then from "I have eight more quarters than dimes"
d+8 = number of quarters
.
Since we know the total:
.10d + .25(d+8) = 6.20
.10d + .25d + 2 = 6.20
.35d + 2 = 6.20
.35d = 4.20
d = 12 (number of dimes)
.
number of quarters:
d+8 = 12+8 = 20
