Answer:
Option (a) is correct.
Explanation:
Given that,
Explicit costs = $10,000
Here, the implicit cost is the cost of sacrificing money income from job:
= $10 per hour × 8 hours a day × 30 days
= $2,400
Revenues:
= Items produced in a day × Selling price of each × 30 days
= 50 × $10 × 30
= $15,000
Therefore,
Economic profit for the month:
= Revenues - Explicit costs - Implicit cost
= $15,000 - $10,000 - $2,400
= $2,600
