Question 519643: What is the equation for... Ginger has five more quarters than dimes. She has $5.10 in change. If she has only quarters and dimes, how many coins of each type does she have? Answer by oberobic(2304) (Show Source):
You can put this solution on YOUR website! When doing coin problems, you have to keep track of the number of coins and their values.
d = number of dimes
10d = value of the dimes in cents
q = number of quarters
25q = value of the quarters in cents
.
10d + 25q = 510 cents
.
q = d+5
