Step-by-step explanation:
To find Wade Ellis' monthly payment for the car loan, we need to calculate the loan amount after the down payment, and then determine the monthly payment using the simple interest formula.
Step 1: Calculate the loan amount after the down payment:
Loan amount = Car price - Down payment
Loan amount = $16,824.89 - (10% of $16,824.89)
Loan amount = $16,824.89 - $1,682.49 = $15,142.40
Step 2: Calculate the monthly payment using the simple interest formula:
Monthly payment = (Loan amount * Interest rate * (1 + Interest rate) ^ Number of months) / ((1 + Interest rate) ^ Number of months - 1)
Where:
- Loan amount is $15,142.40
- Interest rate is 11.5% per year or 0.115
- Number of months is 4 years * 12 months = 48 months
Plugging in the values:
Monthly payment = ($15,142.40 * 0.115 * (1 + 0.115) ^ 48) / ((1 + 0.115) ^ 48 - 1)
Simplifying the equation gives the monthly payment to be approximately $407.46.
