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

He spent 9 dollars and 9 cents so $9.09

Answer 2

Troy spent $9.09.

Explanation:

Troy spent 20 Swiss Francs to stay one night in a youth hostel.

1 U.S. Dollar = 2.2 Swiss franc

We have to convert 20 Swiss franc to U.S. dollars.

So we divide 20 by 2.2 to convert Swiss franc to U.S. dollars.

=
`(20)/(2.2)` = 9.09090909 ≈ $9.09

Troy spent $9.09 to stay one night in a youth hostel.
