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

### Instruction:
 Willie alirudi kutoka Ulaya na euro 70. Kawaida euro 5 inalingana na dola 1, lakini ubadilishaji wa fedha katika uwanja wa ndege utampa Willie 5/7 ya kiwango rasmi cha ubadilishaji. Willie anapata dola ngapi?


### Response:
 Kwanza tujue ni dola ngapi Willie angepaswa kupata kwa kutumia kiwango rasmi cha ubadilishaji: euro 70 / euro 5/dola = $<<70/5=14>>14
Kisha, mnoa kiasi hiki kwa 5/7 ili kujua ni dola ngapi alizopata: 14 dola * 5/7 = $2 * 5= $10
