To find out how much your dinner in Tokyo cost in U.S. dollars, you need to use the exchange rate provided for Japanese yen.

The exchange rate given is:

• Dollars per Japanese yen: 0.009694

The cost of your dinner in Japanese yen is 11,700 yen.

To convert this to U.S. dollars, multiply the amount in yen by the exchange rate:

$\text{Cost in USD} = 11,700 \times 0.009694$
