Answer:
The explicit cost of flight includes cost of fuel, maintenance cost, payment to pilot.
Step-by-step explanation:
The explicit costs are the direct costs incurred during the process of production or business. Here, the payments made to the pilot will be a variable cost, the cost of fuel, etc will be explicit cost.
The marginal explicit cost is the increase in the explicit cost with an additional output. The incremental cost of flight correctly determines the marginal explicit cost.
Opportunity cost is the cost of sacrificing the alternative. Here, the marginal opportunity cost will be the revenue that the firm would have earned by renting the flight to other firms or individuals.
