You can put this solution on YOUR website! Greg started with a certain number of quarters. He then decided on a number of quarters he would save each day. He added the quarters he saved to the amount with which he started. At the end of day 2, Greg had a total of 26 quarters saved. At the end of day 5, he had a total of 35 quarters saved.
--------------------------
# Started with:::: s
# saved each day:: d
----------------
Equation:
s + d = 26
s +4d = 35
--------------------
Subtract and solve for "d":
3d = 9
d = 3 (# added each day)
---
Solve for "s":
s + d = 26
s + 3 = 26
s = 23 (# of quarters started with)
------------------------------------------
