----
Quantity:: q = (5/4)d
Value:: 10d + 25q = 520 cents
-------
Simplify::
5d - 4q = 0
10d + 25q = 520
---------------
Modify for elimination::
10d - 8q = 0
10d + 25q = 520
------------------------
Subtract and solve for "q":
33q = 520
----
Comment: That does not result in a whole
number of quarters. Please check your post.
