Final answer:
Tiffany's monthly payment for the car loan is $204.78 option 1.
Step-by-step explanation:
To find Tiffany's monthly payment, we can use the formula for calculating the monthly payment on a loan:
Monthly Payment = (Principal * Monthly Interest Rate) / (1 - (1 + Monthly Interest Rate)^(-Number of Payments))
In this case, the principal is $10,500 (the total cost of the car after the down payment), the monthly interest rate is 0.00483333 (calculated by dividing the annual interest rate of 5.8% by 12 months), and the number of payments is 48 (4 years * 12 months).
Using these numbers, we can plug them into the formula:
Monthly Payment = (10500 * 0.00483333) / (1 - (1 + 0.00483333)^(-48))
This calculation gives us a monthly payment of $204.78, which matches Option 1.
