Final answer:
The size of the partial payment to finish paying off the loan is $0.00.
Step-by-step explanation:
To find the size of the partial payment to finish paying off the loan, we need to calculate the remaining balance after making 19 monthly repayments of $210.00.
The remaining balance can be calculated using the formula:
Remaining Balance = Total Loan Amount - Total Monthly Repayments
Remaining Balance = $3800.00 - ($210.00 x 19)
Remaining Balance = $3800.00 - $3990.00
Remaining Balance = -$190.00
Since the remaining balance is negative, it means that the loan has already been fully paid off after the 19 monthly repayments.
Therefore, the size of the partial payment to finish paying off the loan is $0.00.
