Final answer:
Dan should produce around 129 knives in each batch to meet the annual demand.
Step-by-step explanation:
To determine how many knives Dan should produce in each batch, we need to find the optimal batch size that minimizes the total cost. Let's break it down:
- Calculate the number of batches needed by dividing the annual demand by the daily production rate: 8,000 / 130 = 61.54 batches.
- Round up the number of batches to the nearest whole number: 62 batches.
- Calculate the average daily demand for each batch: 8,000 / 62 = 129.03 knives.
Therefore, Dan should produce around 129 knives in each batch to meet the annual demand.
