Answer 1

Answer: Option 'a' is correct.

Explanation:

Since we have given that

Amount he exchange in US dollars = 104.51

Amount he exchange for Mexican pesos = 1322.14

So, exchange rate of the US dollar to the Mexican pesos, to three decimal places is given by

`104.51:1322.14\\\\=1:(1322.14)/(104.51)\\\\=1:12.650`

Hence, the exchange rate of the US dollar to Mexican peso is

1:12.650.

Therefore, Option 'a' is correct.
