4. If the output price is $5 per package, the rent for the capital is $50 per truck, and the wage of labor is $100 per worker, what is the profit if 3 trucks are rented and 20 workers are hired?

    A) pi = $3,000

    B) pi = $850

    C) pi = $1,000

    D) pi = $2,150

    E) pi = $600

    A) 15 workers

B) 16 workers   

C) 17 workers

    D) 18 workers    

E) 19 or 20 workers

Solutions

Expert Solution

4) Option B

pi = $850

Calculation of profit if 3 trucks are rented and 20 workers are hired

Revenue(600 * $5) $3000
Less: cost
Capital cost(3 * $50) ($150)
Labor cost(20 * $100) ($2000)
Profit $850

5) Option D

18 workers  

Calculation of profit for different no of workers hired and 5 trucks are rented.

workers 15 workers 16 workers 17 workers 18 workers 19 workers 20 workers
Revenue(total output * $4) $1264 $1792 $2192 $2528 $2820 $3100
Less: cost
Capital cost(5 * $50) ($250) ($250) ($250) ($250) ($250) ($250)
Labor cost(no of workers * $300) ($4500) ($4800 ($5100) ($5400) ($5700) ($6000)
Profit/(loss) ($3486) ($3258) ($3158) ($3122) ($3130) ($3150)

Since there is loss in all level of workers hired, decision should be based on lower loss.when 18 workers a hired loss is lower.
