The table below shows output, marginal cost, and average variable cost for the production of pairs of shoes. All costs are in dollars.
| Output | Marginal
Cost | Average Variable Cost |
| 50 | 60 | 140 |
| 70 | 45 | 115 |
| 90 | 35 | 95 |
| 110 | 30 | 80 |
| 130 | 35 | 65 |
| 150 | 60 | 60 |
| 170 | 105 | 65 |
| 190 | 180 | 75 |
| 210 | 230 | 90 |
| 230 | 290 | 110 |
TABLE 7-6
Refer to Table 7-6. Suppose this firm is producing 210 pairs of shoes per time period and that the variable factor of production is labour. Which of the following statements best describes this firm's production?
◦ Marginal cost is higher than average variable cost, so average product must be rising.
◦ Each additional unit of labour employed reduces the average variable cost of the pairs of shoes.
◦ The firm is producing below its capacity.
◦ Additional units of labour employed will increase the average variable cost of producing shoes.
◦ Marginal cost is higher than average variable cost, so marginal product must be rising.
Primary production is constrained by the most limiting factor.
