Answer 2

Answer: d. 1:1,083.831

Explanation:

Given: Rob is going over his currency exchange receipts from his trip to Japan and South Korea.

The exchange rate of US dollars to Japanese yen is
`1 : 87.441`.

⇒ $1= 87.441 yens

The exchange rate of Japanese yen to South Korean is
`1:12.395.`

⇒ 1 yen = 12.395 won

`\Rightarrow87.441\text{ yens} =87.441*12.395\\\\\Rightarrow87.441\text{ yens} =1083.831195\text {won}`

⇒ $1= 1,083.831195 won

Hence, the exchange rate of US dollars to South Korean won is given by :-

`1:1,083.831195`
