Answer:
a. $300,000
b. $200,000
Step-by-step explanation:
a. The opportunity cost for labor is calculated by multiplying the hours of labor needed to complete the project with the market wage rate.
20,000 hours * $15 per hour = $300,000
b. There are some labors that are unemployed and has agreed to work for $10 per hour. The opportunity cost will now be lower than the previously calculated
20,000 hours * $10 per hour = $200,000
c. The opportunity cost depends on the wage rate of the labor. When the labors are employed at market rate, the opportunity cost is high and when there is unemployment the labors are willing to work for lower wage rate. The opportunity cost is decreased.
