and this problem it gives us d of X is equal to 0.8881 x as they exchange rate to convert euros into US dollars. With ex being your euros and D of X is being your U. S. Dollars. So they want us to find what was the value of U. S. Dollars of 200 euros. So if X equals 200 it wants to know what is d X so d X equals 0.8881 times 200. Multiply those two together Indy of X equals $177.62.
