Question

Jacksons Mom limits the amount of time he is allowed to play video games. After Jackson plays for 9 minutes his mom tells him that he has used 30% of his time. How many more minutes can Jackson play before he uses all of his time?

Answer 1

30 minutes is the amount of time he has left

Answer 2

30% of what is 9...
0.30x = 9
x = 9 / 0.30
x = 30...so its 30 minutes total time

and she has already used 9....so she has (30 - 9) = 21 minutes left
