Answer:
$8146.67
Explanation:
Under the U.S. Rule, unpaid accrued interest is accumulated separately and is not added to principal. In addition, interest is not calculated until a payment is made.
Principal = $12 000.00
1st period = 40 days
Interest on 1st period
= $12 000 × 0.11 × 40/360 Interest = 146.67
Principal + interest = 12 146.67
-Partial payment = 4 000.00
Adjusted balance = $ 8 146.67
Roger's adjusted balance after the first payment is $8146.67.
