Answer: $369,500
Step-by-step explanation:
The Cost concept of accounting calls for the recording of Assets at their cost. 
Clementine Repair services offered to buy the land at $350,500 when it was priced at $388,500.
The seller countered with $369,500 and Clementine accepted this. 
This means that Clementine bought the land for $369,500 which makes it the cost price. 
They should therefore record it at $369,500.
