a. 23 teachers

b. 138 teachers

c. 40 teachers

d. 32 teachers

There were 32 teachers.

Step-by-step explanation:

(215 - 23)/6 = amount of teachers

215 - 23 = 192

192/6 = 32

D. 32 Teachers

Step-by-step explanation:

From the question above, we are dealing with two entities. so I will allocate a letter value to them.

let's use a to represent the number of students and b to represent the number of teachers .

a = number of students

b = number of teachers

from the question there were 23 student more than 6 times the number of teachers.

This can be express mathematically as ;

student number in the spring dance(a) = 23 + 6 × b

The second part of the question talked about the total number of students in the dance  which is 215

Since we know the total number of student that attended the dance, replacing it in the equation is next .

215 = 23 + 6 × b

taking 23 to the left side it becomes minus

215 - 23 = 6b

192 = 6b

divide both side by 6

192/6 = 6b/6

b = 32

Number of teacher that attended the dance is equal to 32

question:

could we have options?

abde or 1,2,4, 5 is the answer
