I suppose that the correct answer could be
2y=7
<h3>Rounding it to the nearest thousand:</h3>
11,000
<h2>Answer:</h2>
11,000
Time spent on Internet + video games = 10 + 13 = 23 hours.
Total free time in a week = 5 * 7 = 35 hours
Percentage = 23/35 * 100 = 65.71%
In short, Your Answer would be 65.71%
Hope this helps!
