You can put this solution on YOUR website! You spend one third of your money on lunch. Your friend then pays back a loan of $2.50. Later, you spend $4 on a movie ticket and $1.25 for a snack. You have $5.25 left. How much money did you have before lunch?"
----
After lunch::
x - (1/3)x = (2/3)x
---
After payback, movie, and snack
(2/3)x+2.5-4-1.25 = (2/3)x -2.75
-----
Equation:
(2/3)x - 2.75 = 5.25
(2/3)x = 8
x = $12
