Answer:
Working for the firm is the best option for Marcie.
Explanation:
Option 1
The implicit value of Marcie is the benefits lost due to his working for a firm.
The implicit cost includes $60,000 of rentals lost, purchase of equipment for $25,000, expenditure of $20,000 on marketing, assistant salary of $30,000 per year and other expenses of $15,000. The revenue that the firm generate is $150,000.
The net benefit = Revenue - Implicit cost
The net benefit = $150,000 - ($60,000 + $25,000 + $20,000 + $30,000 + $15000) = Zero
Option 2
The other option is working for a firm which generates $100,000 in value.
This means the best option here for Marcie is option 2.
