You play video games online. When you sign up with the game site, you get 200 points. You earn 20 more points for each hour that

Savatey [412]

500 = 200 + 20h is our equation.
Subtract 200 from both sides
300 = 20h
Divide by 20
300/20 = 15.
It will take 15 hours to get 500 points.
Hope this helps!
