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?

Respuesta :

$1 = 2.2 Franc
1 Franc = $1 / 2.2
20 Francs = ($1/ 2.2) x 20
Hence,
Troy spend in U.S. dollars  = 9.09 USD.

Answer: [tex]9.09\text{ US dollars}[/tex]

Step-by-step explanation:

Given: The amount spent by Troy to stay one night in a youth hostel= 20 Swiss francs

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

It means 1 US dollar = 2.2 Swiss francs

Thus, 1 Swiss francs =[tex]\frac{1}{2.2}[/tex] US dollar

Therefore, the amount spent by Troy to stay one night in a youth hostel (in US dollars)=[tex]20\times\frac{1}{2.2}=9.090909090\approx9.09\text{ US dollars}[/tex]
