Step 1: Calculate Average Product (AP) and Marginal Product (MP) for each level of labor.
The formulas used are:
- Average Product (AP) = LaborTotalProduct(TP)
- Marginal Product (MP) = ΔLaborΔTotalProduct(TP)
Let's fill in the table:
| Labor (units) | Total Product (TP) (units) | Average Product (AP) (units) | Marginal Product (MP) (units) |
| :------------ | :------------------------- | :--------------------------- | :---------------------------- |
| 0 | 0 | - | - |
| 1 | 10 | 110=10 | 1−010−0=10 |
| 2 | 24 | 224=12 | 2−124−10=14 |
| 3 | 40 | 340≈13.33 | 3−240−24=16 |
| 4 | 50 | 450=12.5 | 4−350−40=10 |
| 5 | 56 | 556=11.2 | 5−456−50=6 |
| 6 | 57 | 657=9.5 | 6−557−56=1 |
| 7 | 56 | 756=8 | 7−656−57=−1 |
| 8 | 52 | 852=6.5 | 8−752−56=−4 |
Step 2: State the completed table.
The completed table is:
Labor(units)012345678TotalProduct(TP)(units)01024405056575652AverageProduct(AP)(units)−101213.3312.511.29.586.5MarginalProduct(MP)(units)−1014161061−1−4
Step 3: Explain the relationship between AP and MP based on the table.
- When Marginal Product (MP) is greater than Average Product (AP) (e.g., at Labor = 2, MP = 14 and AP = 12; at Labor = 3, MP = 16 and AP = 13.33), the Average Product (AP) is increasing.
- The Average Product (AP) reaches its maximum value of approximately 13.33 at Labor = 3. At this point, the MP (16) is still greater than AP (13.33). The exact intersection where MP = AP would occur between Labor = 3 and Labor = 4, where AP starts to fall.
- When Marginal Product (MP) is less than Average Product (AP) (e.g., at Labor = 4, MP = 10 and AP = 12.5; at Labor = 5, MP = 6 and AP = 11.2), the Average Product (AP) is decreasing.
- The Marginal Product (MP) starts to decline earlier than AP, reaching its maximum at Labor = 3 (MP = 16) and then falling, eventually becoming negative (at Labor = 7 and 8).
