Final answer:
To calculate the interest expense for one-half month, divide the annual interest rate by 12 to get the monthly interest rate. Then, multiply the principal amount by the monthly interest rate to find the interest expense for one month. Finally, divide the interest expense for one month by 2 to get the interest expense for one-half month.
Step-by-step explanation:
The interest expense for one-half month is computed based on the annual interest rate on the mortgage payable, which is 8.75 percent. To calculate the interest expense for one-half month, follow these steps:
- Convert the annual interest rate to a monthly interest rate. Divide the annual interest rate by 12 to get the monthly interest rate. For example, 8.75 percent divided by 12 is approximately 0.7292 percent.
- Calculate the principal amount of the mortgage payable. The principal amount is the balance of the cost of the building and land after the down payment. In this case, the principal amount is $119,000 - $11,900 = $107,100.
- Multiply the principal amount by the monthly interest rate to find the interest expense for one month. For example, $107,100 multiplied by 0.7292 percent is approximately $780.09.
- Divide the interest expense for one month by 2 to get the interest expense for one-half month. For example, $780.09 divided by 2 is approximately $390.05.
