Question 890121: Ms. Sanders has a class of 16 students. She can spend $18 on each student to buy math supplies for the year. She first buys all of her students calculators, which costs a total of $108. After buying the calculators, how much does she have left to spend on each student?

You can put this solution on YOUR website! If she spent 108$ for 16 students, that means she spent 108/16=6.75$ per students.
.
So far, she has spent 6.75$ per students. She can spend a total of 18$ on one student, which means she has 18-6.75=11.25$ left to spend per students.
.
Hope that helps.
