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
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

Hence, each student will get an amount of $12.75 to spend on lunch.
-77 = n-4(3-3n)
First you need to distribute the -4
-77 = n-12+12n
then combine like terms
-77 = 13n-12
then switch sides (I dont know, this just makes it easier for me to see)
13n-12=-77
then add 12 to both sides to isolate the variable
13n-12+12=-77+12
13n=-65
Then divide both sides by 13
13n/13=-65/13
n=-5
