Answer:
$75
Step-by-step explanation:
The down payment on the furniture set is 25% of the cash price, which is 0.25 * $900 = $225.
The total amount paid through monthly installments is 6 * $100 = $600.
Therefore, the additional amount paid through hire purchase is $225 (down payment) + $600 (monthly installments) = $825.
To find the additional amount, we subtract the cash price from the total amount paid: $825 (total paid) - $900 (cash price) = $75.
So, the additional amount paid on hire purchase is $75.
