Consumption of A4 paper has been monitored over a period of time and amounts to 1000 boxes per year. Each box costs 10 and each delivery costs 5. The cost of storing the boxes is estimated at 10% of its value per year. What are the economic order quantity, the frequency of ordering and the total annual cost? Please don't answer question if you have already posted a solution as I have received various differing answers and want to get as many opinions as possible. Many thanks.
