Question

On a backpacking trip through Europe, Troy spent 20 Swiss francs to stay one night in a youth hostel. If the foreign exchange rate between the U.S. dollar and the Swiss franc is 1:2.2, how much did Troy spend in U.S. dollars?

Answer 1

Every US Dollar equals $2.2 in France so 9.09.

Answer 2

Answer: Hence, Troy spend 9.09 in U.S. dollars.

Explanation:

Since the foreign exchange rate between the U.S. dollar and the Swiss franc is 1:2.2.

It means,

1 U.S. dollar = 2.2 Swiss Franc

Now, According to question, Troy spent 20 Swiss francs to stay one night in a youth hostel.

So, 1 Swis Franc =
`(1)/(2.2)`

20 Swiss Franc =
`(20)/(2.2)=\$9.09`

Hence, Troy spend 9.09 in U.S. dollars.
