Answer:
$479,500
Step-by-step explanation:
To determine the interest due for the first payment we can solve the following:
interest due on payment 1 = total debt x interest rate x 1/12 = $480,000 x 10% x 1/12 = $4,000
Now we need to subtract the interest due from the first payment:
principal paid = payment - interest due = $4,500 - $4,000 = $500
remaining principal = $480,000 - $500 = $479,500
