Final answer:
The cost of the land is $210,000 after accounting for demolition costs and proceeds from salvaged materials, while the cost of the new building is $1,130,000, which includes the construction costs, architect's fees, and legal fees.
Step-by-step explanation:
When accounting for the purchase and improvement of property, the cost of land and buildings are accounted for separately. The purchase price of the land is $200,000. The demolition costs are typically capitalized to the cost of the land because they prepare the land for its intended use, resulting in an additional $20,000. However, the proceeds from the sale of salvaged materials ($10,000) should be deducted from the cost, leaving the land cost at $210,000.
Expenses that are directly related to the construction of the new building, such as the architect's fees ($35,000), legal fees for title and contract ($5,000), and the construction costs ($1,090,000), should be capitalized to the building. This gives us a total of $1,130,000 for the new building.
Therefore, the correct accounting treatment would record the cost of the land as $210,000 and the cost of the building as $1,130,000. So the answer is option b. $210,000 and $1,130,000.
