There are 300 students in the sixth grade.

Step-by-step explanation:

Percent of students who brought their lunch from home = 80%

Now, number of students who brought their lunch from home is given as:

Now, total number of students is equal to the sum of those who purchased their lunch and those who brought their lunch from home. So,

Therefore, there are 300 students in the sixth grade.

There are 300 students in Sixth grade.

Step-by-step explanation:

Let Total number of students in sixth grade be x.

Number of students who purchased lunch =

Hence There are 300 students in Sixth grade.
