Final answer:
Dan should produce approximately 1,219 knives in each batch.
Step-by-step explanation:
To determine how many knives Dan should produce in each batch, we need to calculate the Economic Order Quantity (EOQ). The EOQ formula is:
Plugging in the numbers, we get:
EOQ = √((2 * 10,500 * 190) / 1.10) ≈ 1,219
Therefore, Dan should produce approximately 1,219 knives in each batch.
