Answer: Each student will get an amount of $12.75 to spend on lunch.
Step-by-step explanation:
Since we have given that
Number of fifth grade students = 90
Amount given by each student to cover admission to the theater = 9.25
So, Total amount given by all of the students is given by
[tex]9.25\times 90=\$832.5[/tex]
Amount given by all of the students for lunch admission =$315
Total amount submitted by the students to the teacher regarding trip is given by
[tex]832.5+315=\$1147.5[/tex]
So, Each student will get an equal amount to spend on lunch is given by
[tex]\frac{1147.5}{90}=\$12.75[/tex]
Hence, each student will get an amount of $12.75 to spend on lunch.
