You can put this solution on YOUR website! Marissa has $4.40 in quarters and dimes. If she has 5 more quarters than dimes, how many of each coin does she have?
------------------
Value:::: 10d + 25q = 440 cents
Quantity: q = d + 5
---
Substitute for "q" and solve for "d":
10d + 25(d+5) = 440
10d + 25d + 125 = 440
35d = 315
d = 9 (# of dimes)
---
Solve for "q":
q = d+5
q = 14 (# of quarters)
