A manufacturing company had been under pressure to increase profits, so it began to produce additional goods. The company was encouraged by the initial increases in revenue, even though profits per item produced were lower than average. Still, total profits increased, so the company decided to make another significant increase in production. This time, however, the profit per item had decreased so much that the company made almost no extra profit from the increase in production. This situation illustrates what concept?
A. Productivity analysis
B. Cross-training
bC. Law of diminishing returns
D. Comparative advantage

Diminishing marginal returns is when a manufacturing firm experiences reduced returns as production increases. According to the theory of diminishing marginal return, a business experiences increased returns with the added inputs until it reaches its maximum production capacity. Additions inputs will not results in more output as production has already reached its peak.

Deploying additional inputs will result in reduced profitability. Inputs are a cost to a business. The additional expenses are not resulting in extra income as output is not increasing. The manufacturing firm was experiencing reduced profits per item because costs were increasing, but income was constant.
