Final answer:
Borrower A owes the bank a total of $24,375 in points.
Step-by-step explanation:
To calculate the amount Borrower A owes the bank in points, we need to first calculate the value of the points.
The value of 1 point can be found by multiplying the loan amount by the value of each point. In this case, Borrower A must pay 2.5% of the mortgage as points, which is equal to 0.025.
So, the value of each point is $390,000 x 0.025 = $9,750.
To calculate the total amount owed in points, we multiply the value of each point by the number of points, which is 21/2 = 2.5.
Therefore, Borrower A owes the bank a total of $9,750 x 2.5 = $24,375 in points.
