Answer:
41%
Explanation:
All of those percentages need to add up to 100
8 + 8 + 13 + 13 + 25 + 33 = 100
Ok...so now that we made sure they all add up to 100, all you need to do is combine the percentage of students sleeping and doing Homework, to get the full percentage for both.
Homework = 8%
Sleeping = 33%
8 + 33 = 41
So the percent of time a student spends and doing homework is 41%.
Hope this helped!
