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

### Instruction:
Willie came back from Europe with 70 euros. Normally 5 euros is worth 1 dollar, but the money exchange at the airport will only give Willie 5/7ths of the official exchange rate. How many dollars does Willie get?

### 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
