Coral buys a house for £234 900 she pays a 10% deposit. Work out the amount of deposit paid by Carol.
Pavel [41]

The solution would be like this for this specific problem:

Given:

Total amount of the house = £234,900

 

<span>Find:

Amount of deposit paid = ?</span>

 

So first, we divide the t<span>otal amount of the house by the percent of deposit that Carol paid.

</span>= £234,900 / 10%

= £23,490

 

<span>Another way to solve this is by converting the percent of the deposit into a decimal. We do this by dividing the percentage amount by 100.

= 10% / 100% </span>

= 0.1

 

Next, we multiply the decimal equivalent of the percentage to the total amount of the house.

= £234,900 * 0.1

= £23,490

 

So, the amount of deposit that was paid by Carol is £<span>23,490.</span>
