Ming plays video games online. When he signed up with the game site, Ming got 200 points. Ming earns 20 more points for each hour that he plays. How many hours does Ming have to play to get to 500 points?

Take 50 and divide it by 2, that will give you 25. Ming will have to play 25 hours of gaming time.

your equation would be y, being 500, = 200 + 20(x), with xbeing hours.

500=200+20x
subtract 200 from both sides
300=20x
divide each side by 20
x=15 He would have to spend 15 hours to get 500 points.
