Answer 2

Answer: c. a total of forty hours a week

Step-by-step explanation:

For Nina to get better grades, she needs to devote more time to studying where she can concentrate on her schoolwork. Currently she sleeps for;

= ( 5 hours * 5 weeknights) + ( 10 * 2 weekends)

= 45 hours.

If she could start sleeping a total of forty hours per week, she would have an extra 5 hours to concentrate more on her school work which would contribute to her grades getting better.
