8. A Forex Bureau in Kenya buys and sells currencies as below:

| Currency | Buying (Kshs.) | Selling (Kshs.) |
|----------|----------------|----------------|
| 1 USD | 144.60 | 146.10 |
| 1 Euro | 133.40 | |

A businessman from America converted 20,730 Euros into Kenyan shillings.

a) Calculate the amount of money in Kenyan shillings that he received. (1 mark)

b) The businessman spent Kshs 2,410,300 while in Kenya. He then converted the remaining Kenyan shillings into US Dollars. Calculate the amount of money, to the nearest US Dollar, that he received. (2 marks)



Answer :

Let's break down the problem step-by-step to find the solution:

### Part (a)
Calculate the amount of money in Kenyan Shillings that the businessman received after converting 20,730 Euros.

- The exchange rate for converting Euros to Kenyan Shillings (Kshs) is 144.60 (buying rate).
- The amount in Euros is 20,730.

To find the amount received in Kenyan Shillings:

[tex]\[ \text{Amount in Kshs} = \text{Amount in Euros} \times \text{Exchange rate} \][/tex]

[tex]\[ \text{Amount in Kshs} = 20730 \, \text{Euros} \times 144.60 \, \text{Kshs/Euro} = 2,997,558 \, \text{Kshs} \][/tex]

So, the businessman received 2,997,558 Kenyan Shillings.

### Part (b)
Calculate the amount of money in US Dollars, to the nearest US Dollar, that the businessman received after spending part of the Kenyan Shillings in Kenya.

- The businessman spent 2,410,300 Kenyan Shillings.
- The remaining amount in Kenyan Shillings needs to be converted to US Dollars.
- The exchange rate for converting Kenyan Shillings to US Dollars (buying rate) is 133.40 Kshs/USD.

First, find the remaining amount of Kenyan Shillings after spending:

[tex]\[ \text{Remaining Kshs} = \text{Total amount in Kshs} - \text{Amount spent} \][/tex]

[tex]\[ \text{Remaining Kshs} = 2,997,558 \, \text{Kshs} - 2,410,300 \, \text{Kshs} = 587,258 \, \text{Kshs} \][/tex]

Next, convert the remaining Kenyan Shillings to US Dollars:

[tex]\[ \text{Amount in USD} = \frac{\text{Remaining Kshs}}{\text{Exchange rate}} \][/tex]

[tex]\[ \text{Amount in USD} = \frac{587258 \, \text{Kshs}}{133.40 \, \text{Kshs/USD}} = 4402.23388305847 \, \text{USD} \][/tex]

Rounding to the nearest US Dollar:

[tex]\[ \text{Amount in USD (Rounded)} = 4402 \, \text{USD} \][/tex]

Therefore, the amount of money the businessman received in US Dollars, to the nearest US Dollar, is 4,402 USD.
