Answer with Step-by-step explanation:
You play video games online.
When you sign up with the game site, you get 400 points.
You earn 50 more points for each hour that you play.
Let we play for x hours.
Then, total points we collect in x hours=400+50x
We have to determine in how many hours do we get to 1,000 points
i.e. the value of x for which
400+50x=1000
50x=600
x=12
Hence, we have to play for 12 hours to get 1,000 points.
