Answer: 240 students
Step-by-step explanation:
For this problem, we know that there are 300 students at this school so we can say that is 100%. Since we know 20% are on the honor roll, then (100% - 20% = )80% are not. Given this, we can say the following:
#ofStudentsNotOnHonorRoll = #ofStudents * %notOnHonorRoll
= 300 * 80%
= 300 * .8
= 240
Hope this helps.
Cheers
