Answer:

This question has incorrect answers but the answer that they are looking for is: 24 hours

Step-by-step explanation:

The average is the total hours divided by the number of weeks

So far Emily has 6 hours for the first 3 weeks, x is the number of hours she needs to work in the 4th week.  

(6+x)/4=10

6+x = 40

x = 34

All the answers they gave are wrong because they did not account for the 4th week while taking averages.
