In the basic EOQ model in Example $12\mathrm{.}1,$ suppose that the fixed cost of ordering is $$500.$ Use Solver to find the new optimal order quantity. How does it compare to the optimal order quantity in the example? Could you have predicted this from Equation $(12\mathrm{.}4)?$

If the lead time in Example $12\mathrm{.}1$ changes from one week to two weeks, how is the optimal policy
