In August of 2008 , Kelly and Tabi took a trip to England and France. At the time of the trip the currency exchange rates were 1 U.S. Dollar per 0.54 British pound ( \( £ \) ) and 1 U.S. Dollar per 0.68 Euro ( \( € \) ). While in London, the girls decided to tour the Tower of London. Tickets cost \( £ 16.50 \) per adult. How much did two tickets cost in U.S Dollars? Two tickets cost \( \$ \)

To find the cost of two tickets in U.S. Dollars, first calculate the total ticket price in British pounds: \( 2 \times £16.50 = £33.00 \). Now, using the exchange rate of 1 U.S. Dollar per 0.54 British pounds, we'll convert it to U.S. Dollars. To do this, we can use the formula: \( \text{U.S. Dollars} = \frac{\text{Amount in pounds}}{\text{Exchange rate}} \). Thus, \( \text{U.S. Dollars} = \frac{£33.00}{0.54} \approx \$61.11 \). So, two tickets cost approximately \( \$61.11 \). Exploring historical landmarks like the Tower of London can transport you back in time! Did you know that this iconic castle has served various purposes throughout its history, including a royal palace, a fortress, and even a prison? It's not just a ticket; it's a gateway to tales of intrigue, power, and royal drama. When planning overseas trips with different currencies, it’s essential to keep an eye on not just the ticket prices but also the exchange rates! One common mistake travelers make is underestimating how these rates can shift, often resulting in unexpected costs. Always check rates close to your departure date, and consider withdrawing cash ahead of time to lock in favorable rates!
