From Sunday to Thursday, Prudence sleeps 6 hours a night. Friday and Saturday she sleeps for 9 hours a night. She also takes a 1-hour nap on Saturday and Sunday. How much sleep does she get in 4 weeks? Think carefully first, then make a decision:
5 nights a week she sleeps for 6 hours so she sleeps 5 * 6 = 30 hours. 2 nights a week she sleeps for 9 hours so she sleeps 2 * 9 = 18 hours. 2 days a week she naps for 1 hour so she sleeps 2 * 1 = 2 hours. Over 1 week she sleeps 30 + 18 + 2 = 50 hours. Over 4 weeks she sleeps 4 * 50 = 200 hours. So, the answer is 200.
