Answer:
70 students
Step-by-step explanation:
If 40% of all students in Mrs. Well's class got an A, and 28 students got an A, that means that 28 = 40%
To find the total number of students, we need to find 100%
40% = 28
Divide by 4
10% = 7
Multiply by 10
100% = 70
So there are 70 students in Mrs. Well's class.
Hope this helps you! :D
