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.

Step-by-step 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.

this doesn't make sense lol
