Question

Shawn received $5 change from $20 when he bought some binders. How many binders did he buy if each binder costs $3?​

Answer 1

5 binders

Explanation:

3 times 5 binders would be 15$, and since he paid with 20$, that is 5 dollars change

As an algbraic equation:

3x+5=20

3x=15

x=5

Answer 2

He would have bought 5 binders. If he got $5 back that would be $20-$5=$15, if each binder cost $3 then 15 divided by 3 equals 5
