108 * 7 = 756
756 * .75 = $567

He is spending $567 on soda, this money could be spent on other things, seeing as the water is free, but instead they do not.
540 times 0.75  equals 405 dollars  over the 3 years 

 52 weeks & not the 36 week school year so its going to be 4000 by 52 equals 76.92 dollars  

3000-2000=1000 
1000 by 40 = $25 a week and 100 month for 10 months
