Sure, I can help you with that!

The first step is to calculate the monthly payment for the loan. We can use the formula for calculating the payment for an installment loan:

Payment = (P * r) / (1 - (1 + r)^-n)

where:

  • P is the loan amount ($17,000 in this case)
  • r is the monthly interest rate (which is the annual interest rate divided by 12)
  • n is the total number of payments (which is the number of years multiplied by 12)

So for this loan, we have:

  • P = $17,000
  • r = 5.5% / 12 = 0.00458333 (rounded to 8 decimal places)
  • n = 4 * 12 = 48

Substituting these values into the formula, we get:

Payment = (17,000 * 0.00458333) / (1 - (1 + 0.00458333)^-48) = $395.03 (rounded to 2 decimal places)

So the monthly loan payment is $395.03.

Now, let's look at the income statement for September. We made a down payment of $3,000, so the cash expenditure for the car purchase is $3,000. There is no loan payment in September because the first payment is usually due one month after the loan is disbursed.

For the subsequent monthly income statements, we will show a loan payment of $395.03. This payment will consist of two parts: principal and interest. The interest part of the payment will decrease over time as the loan balance decreases, while the principal part of the payment will increase. The total monthly payment will remain the same throughout the term of the loan.

So the correct answer is (A) $395.
