Final answer:
Mr. Jernigan's accounting costs for farming corn are $15,000, which include expenses for seeds, fertilizer, and pesticides. His economic costs are $55,000, which include his accounting costs plus the forgone salary from alternative employment and the potential rental income from the land.
Step-by-step explanation:
Accounting costs refer to the direct expenses Mr. Jernigan incurs while farming. His accounting costs for farming the corn include the monetary expenses for seed ($2,000), fertilizer ($7,000), and pesticides ($6,000). Therefore, the total accounting costs equate to $15,000 ($2,000 + $7,000 + $6,000).
Economic costs, on the other hand, include both the explicit costs (like those mentioned above) and the opportunity costs associated with the production. Mr. Jernigan's opportunity cost includes the forgone salary from selling insurance ($25,000) and the rent he could earn by renting out the land ($15,000). Adding these opportunity costs to the accounting costs, his total economic costs would be $55,000 ($15,000 + $25,000 + $15,000).
