Question

The school is taking 80 students to the state fair for a field trip. There are students going from three different classes. Mr. Johnson’s class has 27 students and Mrs. Martinez’s class is taking 31

students.

Which equation would represent how many students are selected from Mr. Garcia’s class?

A.

27+31=80+x

B.

80=27+31+x

C.

80+27=31−x

D.

x=80+(31−27)

Answer 1

The sum of the three classes must equal 80.
We know that the number of students going are 27 and 31.
So add those amounts together plus the unknown number in Mr. Garcia's class (x) and set = 80
27 + 31 + x = 80
LETTER B
27 + 31 + x = 80

Answer 2

I very much believe it is C but not quite sure
