Question

What is the anwser and how do I solve this?

Answer 1

Answer: A) 480

Step-by-step explanation:

The information that we have is:

Total number of students: 1200

25% are 8th grade

35% are 7th grade

the rest is 6th grade.

To find the percentage that corresponds to 6th grade, we substract 25% and 35% from 100%:

`100-25-35=40`

So 40% of the students are 6th graders.

Now to find how much students this is, we need to divide the total number od students by 100, and then multiply by 40:

`(1200)/(100)(40)=12(40)=480`

the answer is A)480
