If you have 21 more Quarters than Nickels and your total is $15.45, how many of each coin do you have?
----------------------------
Equations:
Quantity Eq::: q = n+21
Value Eq::::::5n+25q = 1545 cents
---------------------------------------
Substitute for "q" and solve for "n":
5n + 25(n+21) = 1545
30n = 1545-25*21
30n = 1020
n = 34 (# of nickels)
q = n+21 = 55 (# of quarters)
