Final Answer:
No, the sale of the gas station does not qualify as the retirement of a tangible long-lived asset.
Step-by-step explanation:
The sale of a gas station, even if it involves a foreseeable expense such as installing new gas lines, does not meet the criteria for the retirement of a tangible long-lived asset. In accounting, the retirement of a tangible long-lived asset typically refers to the removal or disposal of the asset from service without receiving any significant economic return. In this scenario, the sale of the gas station involves a transfer of ownership and is associated with a consideration (the sale price), making it a different financial transaction compared to the retirement of an asset.
While the installation of new gas lines is an expense related to the sale, it does not alter the nature of the transaction as a sale rather than a retirement.
