Low Attendance is our Super Power
First so we can see how much money we will save we need to estimate using some numbers. First, I got the attendance rate and found that it was about 84% which was extremely low! With that I found out that the max of classes we would join to another class would be 16%. I decided that we would probably have some problems with doing it perfectly, so I reduced it to about half the amount to get a realistic number of joint classes.
Next, I Got the number of teachers that worked full time which was 58.8. after that I got the average base teacher salary (indeed.com) and it was $87,295 per year. I times that by the amount of full-time teachers which was $5,132,946 then I times that by 8% to find how much I would save.
