Step-by-step explanation:
Converting USD to Japanese Yen
To convert 100 USD to Japanese yen, we need to use the exchange rate between these two currencies. Although the exchange rate can fluctuate frequently due to economic factors and investor sentiment, let's assume you have access to the most current rate. If the latest exchange rate is X yen per dollar, the expression to calculate the amount in yen would be:
100 USD * X yen/USD = Y yen
Just replace X with the current exchange rate to find out how many yen 100 USD is worth. For instance, if the current exchange rate is 110 yen per dollar, the calculation would be:
100 USD * 110 yen/USD = 11,000 yen
This calculation will give you the amount of Japanese yen you'd receive in exchange for 100 USD, considering the current market rate provided.
