### Instruction:
Harry is counting the hours that he sleeps. On Monday night, he sleeps for 8 hours. On Tuesday night, he sleeps for 7 hours. On Wednesday night, he sleeps for 8 hours. On Thursday night, he sleeps for 10 hours. On Friday night he sleeps for 7 hours. What is the average number of hours that Harry sleeps in one night?

### Response:
Across Monday through Friday, the total number of hours Harry sleeps is 8 + 7 + 8 + 10 + 7 = <<8+7+8+10+7=40>>40 hours.
This means that, on average, he sleeps for 40 / 5 = <<40/5=8>>8 hours in one night.
