Kendra has $13.20 in dimes and quarters. If she has 4 times as many quarters as dimes, how many of each coin does she have?
----------------------------
Quantity: q = 4d
Value: 25q+10d = 1320 cents
-------------------------
Substitute for "q" and solve for "d":
25(4d) + 10d = 1320
110d = 1320
d = 12 (# of dimes)
----
q = 4d = 48 (# of quarters)
-----------------------------
