Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
Nathan plays amateur baseball. He played for 3 hours for two weeks, every day. His friend Tobias played for 5 hours every day, but only for one week. How many hours did Nathan and Tobias play in total?

### Response:
Two weeks are 14 days, so Nathan played for 3 * 14 = <<14*3=42>>42 hours.
Tobias played for 7 days, so he played a total of 5 * 7 = <<5*7=35>>35 hours.
Nathan and Tobias played together for 35 + 42 = <<35+42=77>>77 hours.
