Final answer:
Carlton's basis for the land and improvements is $1,413,000.
Step-by-step explanation:
Carlton's basis for the land and improvements can be calculated by adding up the purchase price of the land, legal fees, broker's commission, and additional legal fees for rezoning. Then, the cost of subdividing the land and installing streets and sewers should be added.
The calculation is as follows:
- Purchase price of the land: $550,000
- Legal fees: $10,000
- Broker's commission: $28,000
- Additional legal fees for rezoning: $25,000
- Cost of subdividing the land and installing streets and sewers: $800,000
Adding all these costs, the basis for the land and improvements is $1,413,000. Therefore, the correct answer is d. $1,413,000.
