Ming plays video games online.
when he signed up with the game site, ming got 200
200
points.
ming earns 20
20
more points for each hour that he plays.

how many hours does ming have to play to get to 500
500
points?

15 hours

Step-by-step explanation:

This if from ttm, but I'll explain anyways.

Since the question is asking how many more hours 'till Ming would have 500 points, you subtract 200 from 500. That would result with the number 300. You get 20 points per hour. So 300 divided by 20 would be 15.

is there any other information given for this problem? this is not enough information.
