Question

In his free time, Gary spends 8 hours per week on the Internet and 10 hours per week playing video games. If Gary has five hours of free time per day, approximately what percent of his free time is spent on the Internet and playing video games?

Answer 1

find how much free time he has per week
assuming our week has 7 days and he even does this on Saturday ad Sunday,

freetimetotal in 1 week=freetime per day times 7=5*7=35


so percent free time spent on video games and internet=(videogames+internet)/totaltimeperweek=(8+10)/35=18/35≈0.514≈51%

the answer is A. 51%

also, regarding how much he's playing:

Answer 2

He spent a total of 22.85+28.57 = 51.42 % of his free time o internet and videogames.

Explanation:

If Gary has 5 hours of free time per day, he has 5*7=35 hours of free time per week.

Now, in the case of internet:

`(35h)/(8h)= (100)/(x)`

`x= (8*100)/(35)`

x= 22.85% spent on internet.

In the case of videogames:

`(35h)/(10h)= (100)/(x)`

`x= (10*100)/(35)`

x= 28.57% spent on internet.
