Answer:
Diseconomies of scale due to the fact that per unit cost increased from $25 to $39.92
Step-by-step explanation:
Economies is scale is when a larger production is a product leads to reduced cost of production.
For example if production of 1,000 units of a good costs $20 per unit, but production of 1,500 units goes for $17. The cost of production per unit reduces. So there is economies of scale.
In the given scenario production of 5,000 units is at $25 per unit.
While at 5,100 units it is (2,000,000 ÷ 50,100) = $39.92
So this is a diseconomies of scale.
