Without calculating the? EOQ, how can you conclude from these two calculations that the current lot size is too? large?

A. When Q? = 505?, the annual holding cost is larger than the ordering? cost, therefore Q is too large.

B. Both quantities are appropriate.

C. There is not enough information to determine this.

D. When Q? = 505?, the annual holding cost is less then the ordering? cost, therefore Q is too small.

E. What would be the annual cost saved by shifting from the 505?-bag lot size to the? EOQ?

The annual holding cost with the EOQ is ?$
