In his free time, Gary spends 14 hours per week on the Internet and 14 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?

The answer is 80%

If Gary has 5 hours of free time per day, he has 35 hours of free time per week.

1 week = 7 days

1 day = 5 h of free time

1 week = 7 * 5h of free time = 35h of free time

Gary spends 14 hours per week on the Internet and 14 hours per week playing video games. That is total 28 hours (14 + 14 = 28)

So, the percent of his free time is spent on the Internet and playing video games is:

28/35*100% = 80%
