Question

If Gary spends 10 hours per week on the internet and 9 hours per week playing video games. If Gary has 5 hours of free time per day what percent of his free time is used on video games and the internet?

Answer 1

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:

$percent = \frac{\text{ Time spent per week on internet and video game }}{\text{ 35 hours of free time per week}} \times 100$

$percent = \frac{19}{35} \times 100 = \frac{1900}{35}\\\\percent = 54.286 \approx 54$

Thus 54 % of his free time is used on video games and internet
