Ruby-Star Incorporated is considering two different vendors for one of its top-selling products which has an average weekly demand of
70
units and is valued at
$90
per unit. Inbound shipments from vendor 1 will average

Sam's Pet Hotel operates 50 weeks per year, 6 days per week, and uses a continuous review inventory system. It purchases kitty litter for $13.00 per bag. The
following information is available about these bags:
> Demand 75 bags/week
> Order cost = $52.00/order
> Annual holding cost = 20 percent of cost
> Desired cycle-service level = 80 percent
>Lead time = 5 weeks (30 working days)
> Standard deviation of weekly demand = 15 bags
> Current on-hand inventory is 320 bags, with no open orders or backorders.
a. Suppose that the weekly demand forecast of 75 bags is incorrect and actual demand averages only 50 bags per week. How much higher will total costs be, owing
to the distorted EOQ caused by this forecast error?
The costs will be $higher owing to the error in EOQ. (Enter your response rounded to two decimal places.)
