Angelita has 5 more dollar bills than quarters. Her money totals 21.25 dollars. How many of each does she have?
--------
Equations:
d = q + 5
100d + 25q = 2125 cents
-----------------------------
Modify::
d - q = 5
4d +q = 85
--------------
Add and solve for "d"::
5d = 90
d = 18 (# of dollar bills)
q = d-5 = 13 (# of quarters)
