John has been having trouble sleeping lately. In the past week he was only able to get 3 hours of sleep on 2 of the days and on the remaining days he was only able to get 60% of the recommended 8 hours of sleep. How much sleep did he get this week? Let's think first. Chain of thought:
User
For the 2 days he gets 2 * 3 = 6 hours. He gets 60% of the recommended amount for 7 - 2 = 5 days. On those days he gets 8 * .6 = 4.8 hours. So he gets 5 * 4.8 = 24 hours. So he gets a total of 24 + 6 = 30 hours of sleep.
Therefore, the answer is 30.
