Question

The number of students that earn straight A's decreases by half

each year. Currently there are 20 students who have all A's. Write
an equation to represent this scenario.

Answer 1

Explanation:

20 ÷ 2 = S

S represents the students that have straight A's the next year. You would simply divide the current number of students by 2 and it will give you half the student number you had before. And those are the students who still are getting straight A's.
