In his free time, Gary spends 13 hours per week on the Internet and 8 hours per week playing video games. If Gary has five hours of free time per day, what percent of his free time is spent on the Internet and playing video games?

First let's find the total amount of free time he has in 7 days or one week.

5 * 7 = 35 hours of free time

Now we need to add the 8 hours for video games to the 13 hours of internet

8 + 13 = 21

To find the percent we can use this formula

21/35 = x/100 we can simplify 21/35 to 3/5 so it would be

3/5 = x/100 We cross multiply to get 5x = 300

x = 60

60% of his free time is spent on the internet and playing video games.
