Answer:
$185,600
Step-by-step explanation:
The cost of the land includes all the expenses that represent an essential part of either the land itself, or the transaction. In this case, this would be:
$175,000 in cash for the land itself.
$4,800 in property taxes due.
$1,600 in attorney fees (without the attorneys, the transaction could not have been completed).
and $4,200 for grading the land (the grading is a process inseparable from the land itself).
If we add these figures we obtain the correct answer of $185,600.
The parking lot, on the other hand, is an entity, or property, that is separate from the land, and its cost of $15,000 is not added to the cost of the land. The parking lot is in fact, a fixed asset that will be depreciated accross time, because the paving of a parking lot deteriorates, whereas the land cannot be depreciated because land, or terrain, are considered to be assets with unlimited useful life.
