A property valued at $390,000 has improvements with straight-line depreciation over 39 years. How much have the improvements depreciated after 10 years?

To calculate the depreciation of improvements on a property using straight-line depreciation, you first need to determine the annual depreciation amount. The straight-line depreciation method spreads the cost of an asset evenly over its useful life.

In this case, the improvements have been valued at $390,000, and they depreciate over a period of 39 years. The annual depreciation can be calculated by dividing the total value of the improvements by the number of years of useful life. This gives:

Annual Depreciation = Total Value of Improvements / Useful Life Annual Depreciation = $390,000 / 39 = approximately $10,000 per year.

After 10 years, the total depreciation would be calculated by multiplying the annual depreciation amount by the number of years:

Total Depreciation after 10 years = Annual Depreciation * Number of Years Total Depreciation after 10 years = $10,000 * 10 = $100,000.

This indicates that after 10 years, the improvements have depreciated by $100,000. Thus, the correct answer reflects the total amount of depreciation that has occurred over that period.
