Average demand = 36 units per day
Average lead time = 50 days
Item unit cost = $70 for orders of less than 400 units
Item unit cost = $68 for orders of 400 units or more
Ordering cost = $45
Inventory carrying cost = 25%
The business year is 250 days
Assume there is no uncertainty at all about the demand or the lead time.
- Calculate EOQ if unit cost is $70 and $68. (Note: These EOQs do not need to be feasible in theirprice range.) (Round up your answers to the next whole number.)
