Given:
Sticker price of car = $10,000
His options will cost him extra 15% = 0.15
Percentage discount = 10% = 0.10
Down payment = 25% = 0.25
Let's solve for the following:
• (a). Find Fitzwilliam's down payment on the car.
Given that his options will cost him extra 15% and he got a percentage discount of 10%, the total amount he will pay for the car will be:
[tex]\begin{gathered} T=10000(1+(0.15-0.10)) \\  \\ T=10000(1+0.05) \\  \\ T=10000(1.05) \\  \\ T=10500 \end{gathered}[/tex]
The total cost of the car will be $10,500
Now, to find the down payment, we have:
Down payment = 25% of Tottl cost
Down payment = 0.25 x 10500
Down payment =2625
Therefore, his down payment s  $2625 
• (,b). Find the balance that Fitzwilliam needs to finance.
To find the amount he needs t balance, apply the formula:
Balance = Total cost - down payment
Balance = 10500 - 2625 
Balance = 7875
Therefore, the balance he will need to finance is  $7875 
ANSWER:
(a). $2625
(b). $7875
