Answer:
-$11,000 is the economic profit or we can say it is a loss.
Step-by-step explanation:
The job paid Bob = $100000
The insurance cost is = $8,000
The material cost is = $15,000
The lease payments are = $8,000
The sales revenue is $120,000.
So, Bob's economic profit is: [tex]120000-100000-8000-15000-8000=-11000[/tex]
Therefore, his economic profit is -$11000.
