Answer 1

7 U.S. dollars ($) would be equivalent to approximately ¥806 Japanese yen.

Step-by-step explanation:

To find out how many Japanese yen are equivalent to 7 U.S. dollars, we can use the given exchange rates. First, we need to find the equivalent amount in euros:

`\[ 7 \, \text{USD} * \left( \frac{90 \, \text{euros}}{100 \, \text{USD}} \right) = 6.3 \, \text{euros} \]`

Now, we can convert euros to Japanese yen using the exchange rate of 1 euro to 128 Japanese yen:

`\[ 6.3 \, \text{euros} * 128 \, \text{yen/euro} = 806.4 \, \text{Japanese yen} \]`

Therefore, 7 U.S. dollars would be approximately equivalent to ¥806 Japanese yen. The calculations involve basic conversion using the given exchange rates, ensuring that the units cancel out correctly to arrive at the desired currency. This process allows us to navigate through multiple currency conversions, providing an accurate and precise answer to the question.
