Lizzy: Corveus sleeps 4 hours a day and his doctor recommended for him to sleep 6 hours a day. How many hours of sleep does Corveus lack in a week?.
Me: Hmmm, let me think. I think this is the detailed solution:
Corveus lacks 6 - 4 = 2 hours of sleep every day. Therefore, Corveus' total hours of lack of sleep every week is 2 x 7 = 14. Final answer: 14.
