Andre candess manages an office supply store. one product in the store is computer paper. andre knows that 10,000 boxes will be sold this year at a constant rate throughout the year. there are 250 working days per year and the lead-time is 3 days. the cost of placing an order is $30, while the holding cost is $15 per box per year. if andre orders 500 boxes each time he orders from his supplier, what would his total annual inventory cost be (holding cost plus ordering cost)?
