Answer:
There are 250 students.
Step-by-step explanation:
I reasoned....
If 24% purchased their lunch, then 76% brought their lunch -- because 100% (the total) - 24% = 76%.
So, I set up this up to find the missing number:
190 x
------ = ------
76% 24%
190 x 24 = 4,560
4,560 / 76 = 60
So, x = 60 students, which represents the 24% of students who purchased their lunch.
190 + 60 = 250
