54 % of his free time is used on video games and internet
Solution:
Given that Gary spend 10 hours per week on the internet and 9 hours per week playing video games
Gary has 5 hours of free time per day
We know that, 1 week = 7 days
5 hours of free time per day, So for 1 week get,
7 x 5 = 35 hours of free time per week
Time spent per week on internet and video game = 10 + 9 = 19 hours per week
The percent of free time used on video games and internet is:
[tex]percent = \frac{\text{ Time spent per week on internet and video game }}{\text{ 35 hours of free time per week}} \times 100[/tex]
[tex]percent = \frac{19}{35} \times 100 = \frac{1900}{35}\\\\percent = 54.286 \approx 54[/tex]
Thus 54 % of his free time is used on video games and internet
