Kendra has $4.25 in dimes and quarters. If she has 3 times as many quarters as dimes, how many of each coin does she have?
-----
Quantity Equation: q = 3d
Value Equation: 10d + 25q = 425 cents
---------------------------------------
Substitute for "q" and solve for "d":
10d + 25(3d) = 425
85d = 425
d = 5 (# of dimes)
----
Solve for "q":
q = 3d
q = 15 (# of quarters)
-------------------------
