Introduction

As the summer months approach, many of us are planning our next holiday destination. For Doris, the excitement is building as she prepares to embark on a thrilling adventure to America. However, before she can indulge in the country's rich culture, delicious food, and breathtaking landscapes, she needs to take care of some essential preparations. One of these is exchanging her British pounds into the local currency, the US dollar. In this article, we will delve into the world of currency exchange and explore how Doris can calculate the amount of dollars she will receive when changing £280 into the US currency.

The Exchange Rate: A Crucial Factor

The exchange rate is a fundamental concept in currency exchange, and it plays a vital role in determining the value of one currency in relation to another. In this case, the exchange rate is £1.00 = $1.06, which means that for every British pound, Doris can exchange it for $1.06 in US dollars. This rate is crucial in calculating the amount of dollars she will receive when changing her £280 into the US currency.

Calculating the Amount of Dollars Received

To find the amount of dollars Doris receives, we need to multiply the number of British pounds she is changing (£280) by the exchange rate ($1.06). This can be represented mathematically as:

£280 × $1.06 = $298.80

Therefore, when Doris changes £280 into dollars, she will receive $298.80.

Rounding to the Nearest Cent

As the problem requires the answer to be correct to the nearest $0.01, we need to round the calculated amount to two decimal places. In this case, $298.80 is already rounded to the nearest cent, so the final answer remains the same.

Conclusion

In conclusion, Doris's holiday in America is just around the corner, and she has successfully calculated the amount of dollars she will receive when changing £280 into the US currency. With the exchange rate of £1.00 = $1.06, she can confidently exchange her British pounds and enjoy her time in America, knowing that she has taken care of the essential preparations.
