Table 3-PEX2: A Production Function with Capital and Labor
Capital 6 346 490 600 692 775 846
(trucks) 5 316 448 548 632 705 775
4 282 400 490 564 632 692
3 245 346 423 490 548 600
2 200 282 346 400 448 490
1 141 200 245 282 316 346
15 16 17 18 19 20
Labor (workers)
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
5. If now the output price is $4/package, the rent is $50/truck, and the wage is $300/worker, and if 5 trucks are being rented, how many workers should be hired?
A) 15 workers
B) 16 workers
C) 17 workers
D) 18 workers
E) 19 or 20 workers
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.
