Introduction

As James prepares to return home from his holiday in the USA, he finds himself in a predicament. He has his eyes on a gift in a shop at the airport, but the price is £65. However, he can purchase the same gift online for £60, including delivery. The question is, is it worth buying the gift online or paying the higher price at the airport? To make an informed decision, we need to consider the exchange rates and the cost of the gift in both scenarios.

The Exchange Rates

On the day of his flight, the exchange rates were as follows: £0.80 = $1. This means that for every £1 James has, he can exchange it for $1.20. To calculate the cost of the gift in dollars, we need to divide the price in pounds by the exchange rate.

Calculating the Cost of the Gift in Dollars

Let's calculate the cost of the gift in dollars using the exchange rate.

Price of the gift in pounds: £65
Exchange rate: £0.80 = $1
Cost of the gift in dollars: £65 ÷ £0.80 = $81.25

Comparing the Prices

Now that we have the cost of the gift in dollars, we can compare the prices of the gift in both scenarios.

Price of the gift at the airport: £65
Price of the gift online: £60 (including delivery)
Cost of the gift in dollars at the airport: $81.25
Cost of the gift in dollars online: $60 ÷ £0.80 = $75

The Verdict

Based on the calculations, it appears that buying the gift online would be the more cost-effective option. The price of the gift online is £60, which is £5 less than the price at the airport. Additionally, the cost of the gift in dollars online is $75, which is $6.25 less than the cost at the airport.

Conclusion

In conclusion, James should consider buying the gift online to take advantage of the lower price and the convenience of delivery. However, it's essential to note that this calculation assumes that the exchange rates remain the same and that there are no additional fees associated with buying the gift online.

Q: What is the difference between an exchange rate and a conversion rate?

A: An exchange rate is the rate at which one currency is exchanged for another, while a conversion rate is the rate at which a quantity is changed from one unit to another. In other words, an exchange rate is the price of one currency in terms of another, while a conversion rate is the factor by which a quantity is multiplied to change its unit.

Q: How do I calculate the exchange rate?

A: To calculate the exchange rate, you need to know the price of one currency in terms of another. For example, if the exchange rate is £0.80 = $1, this means that for every £1 you have, you can exchange it for $1.20.

Q: What is the formula for converting currencies?

A: The formula for converting currencies is:

Currency 1 (in local currency) x Exchange Rate = Currency 2 (in foreign currency)

For example, if you want to convert £65 to dollars using the exchange rate £0.80 = $1, the formula would be:

£65 x £0.80 = $52

Q: How do I calculate the cost of a product in a foreign currency?

A: To calculate the cost of a product in a foreign currency, you need to know the price of the product in the local currency and the exchange rate. For example, if the price of a product is £65 and the exchange rate is £0.80 = $1, the cost of the product in dollars would be:

£65 x £0.80 = $52

Q: What is the difference between a fixed exchange rate and a floating exchange rate?

A: A fixed exchange rate is a rate that is set by a government or a central bank and remains the same for a certain period of time. A floating exchange rate, on the other hand, is a rate that is determined by the market forces of supply and demand and can fluctuate constantly.
