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

### Instruction:
 Nathan anacheza mpira wa miguu wa hobi. Alicheza kwa masaa 3 kwa wiki mbili, kila siku. Rafiki yake Tobias alicheza kwa masaa 5 kila siku, lakini kwa wiki moja tu. Jumla ya masaa wangapi Nathan na Tobias walicheza?


### Response:
 Wiki mbili ni siku 7 * 2 = <<7*2=14>>14.
Nathan alicheza kwa masaa 3 * 14 = <<3*14=42>>42.
Tobias alicheza kwa masaa 5 * 7 = <<5*7=35>>35.
Nathan na Tobias walicheza pamoja kwa jumla ya masaa 42 + 35 = <<42+35=77>>77.
