Step-by-step explanation:
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>
