Further explanation </h3>
<u>Given:</u>
Number of students = 90 students
Each student gives $9.25 for admission and lunch
Admission for all students = $315
Each student will get an equal amount to spend on lunch.
<u>Question:</u>
How much will each fifth grader get to spend on lunch?
First step, we need to calculate the total amount the students gave to the teacher for admission and lunch
![\boxed {90 \times 9.25 = 832.5}](https://tex.z-dn.net/?f=%5Cboxed%20%7B90%20%5Ctimes%209.25%20%3D%20832.5%7D)
then we will calculate the total amount for lunch
![\boxed {832.5 - 315 =517.5 }](https://tex.z-dn.net/?f=%5Cboxed%20%7B832.5%20-%20315%20%3D517.5%20%7D)
that is the total amount for lunch for all the students. To calculate how much each student get spend on lunch
![\boxed {= \frac{517.5}{90} }\\\boxed {= 5.75 }](https://tex.z-dn.net/?f=%5Cboxed%20%7B%3D%20%5Cfrac%7B517.5%7D%7B90%7D%20%7D%5C%5C%5Cboxed%20%7B%3D%205.75%20%7D)
So, each student wil get $5.75 to spend on lunch.
