Question

Walter went to Japan for a business trip. Walter converted $ 900 US into 80,514 Yen at the local bank. Walter spent 53,944 Yen on this trip and returned with the remaining Yen to the US.Find the remaining amountRound answer to the nearest whole dollar.

Answer 1

$297

Step-by-step explanation:

Amount taken for the trip = $900 US

Converting to Yen, amount = 80,514 Yen

Amount spent = 53,944 Yen

Amount remaining + Amount spent = Total amount for the trip

Amount remaining + 53944 = 80514

Amount remaining = 80514 - 53944

Amount remaining = 26570 Yen

We need to convert back to US dollars:

if 80,514 Yen = $900 US

let 26570 Yen = y

Cross multiply:

`\begin{gathered} y(80514\text{ Yen) = \$900 (}26570\text{Yen)} \\ y\text{ = }\frac{\text{ \$}900\text{ }*\text{ }26570}{80514} \end{gathered}`
`y\text{ = \$297.00}`

The remaining amount aftert the trip is $297 (nearest whole dollar)
