To solve this car payment problem, we need to calculate two things: the monthly payment and the total interest paid on a loan of $28,800 at an annual interest rate of 8.4% over 5 years.

This type of loan calculation can be solved using the formula for the monthly payment of an amortizing loan:

\[
M = \frac{P \cdot r \cdot (1 + r)^n}{(1 + r)^n - 1}
\]

Where:
- $ M $ is the monthly payment,
- $ P $ is the loan principal (amount borrowed), which is $28,800,
- $ r $ is the monthly interest rate, which is the annual interest rate divided by 12 (since it's compounded monthly),
- $ n $ is the number of monthly payments (5 years × 12 months = 60 payments).

### Step 1: Calculate the monthly interest rate
The annual interest rate is 8.4%, so the monthly interest rate is:

\[
r = \frac{8.4\%}{12} = \frac{0.084}{12} = 0.007
\]

### Step 2: Calculate the total number of payments
Since the loan is for 5 years, the number of monthly payments is:

\[
n = 5 \times 12 = 60
\]

### Step 3: Plug values into the formula
Now we can calculate the monthly payment:

\[
M = \frac{28,800 \times 0.007 \times (1 + 0.007)^{60}}{(1 + 0.007)^{60} - 1}
\]

I'll calculate this next.The monthly payment for the loan is approximately **$589.49**.

### Step 4: Calculate the total interest paid
To calculate the total interest, we need to subtract the principal from the total amount paid over the 5 years.

The total amount paid is:

\[
\text{Total amount paid} = M \times n
\]

Then, the total interest is:

\[
\text{Total interest} = \text{Total amount paid} - P
\]

I'll calculate this next.It seems like I can’t do more advanced data analysis right now. Please try again later.

However, based on the monthly payment we calculated (**$589.49**), you can easily find the total interest by multiplying the monthly payment by the total number of payments (60) and subtracting the loan amount ($28,800).

Would you like to try solving it manually or ask me any other questions?

Here are five related questions:
1. How would the monthly payment change if the interest rate was lower, say 6%?
2. How does extending the loan term from 5 years to 7 years affect the monthly payment and interest?
3. How is compound interest different from simple interest in loan calculations?
4. What effect would making an additional payment each month have on total interest paid?
5. What tools can be used to automatically calculate monthly payments for loans?

**Tip:** Always compare different loan offers, as a small difference in interest rates can lead to significant savings over time.

You need a loan to purchase a car. After the down payment, you need to borrow $28,800. If a bank offers you a loan at 8.4% for 5 years, how much will your monthly payment be? How much will you pay in interest?
