Question #2: The college that is drawing the most investment income in 2008 takes in approximately how much in mean total income per student in 2008? (Total income = tuition + investments)

"mean" is the same as average

"mean total income per student" = (TOTAL income)/(# of students)

Similar example: let's say that there a school has 3000 trees and 100 students.

We can say that the mean number of trees per student = 3000/100 = 30

In other words, there are 30 trees per student.

Does that help?

## Yes indeed!

mean total is basically sum, and if "what is per quantity from total?", then sum/number of quantity.

But mistakenly i thought need to calculate mean for all 15 school
