Assume that your aunt sold her house on December 31, and to help close the sale she took a second mortgage in the amount of $30,000 as part of the payment. The mortgage has a quoted (or nominal) interest rate of 6%; it calls for payments every 6 months, beginning on June 30, and is to be amortized over 5 years. Now, 1 year later, your aunt must inform the IRS and the person who bought the house about the interest that was included in the two payments made during the year. (This interest will be income to your aunt and a deduction to the buyer of the house.) To the closest cent, what is the total amount of interest that was paid during the first year? Do not round intermediate calculations. Round your answer to the nearest cent.
