Final answer:
The student's query does not directly relate to the leasing details provided about Delia Inc. and Lee Inc., but instead asks about a firm's economic profit concerning the opportunity cost of land ownership. To accurately calculate economic profit, additional financial details are required.
Step-by-step explanation:
A student has mentioned that Delia Inc. leases equipment to Lee Inc., with the lease involving a fair value of $100,000 and a carrying value of $80,000. The equipment has an economic life of four years and the lease term is three years, with an incremental borrowing rate of 10%.
Additionally, there is a purchase option for Lee to buy the equipment at the end of the lease for $10,000, which is expected to be taken. The annual lease payment is $33,809.39, paid upfront. However, the actual question about the firm’s economic profit, seems to refer to an unrelated business matter where a firm's factory is on self-owned land which could be rented for $30,000 per year. To calculate economic profit, one would need more information such as the firm’s total revenue and total costs, including the opportunity cost of using the land instead of renting it out.
