Question 2: Metro Tech buys three components from a local wholesaler. The annual demand
for components A, B, and C is 500, 3000, and 6000 units respectively. The agreed purchase
price is $20, $15, and $10per unit for A, B, and C respectively for each product. The holding
cost is estimated to be 20% per year. The ordering cost consists of handling and trucking
costs. The handling cost is $100 for each type of component regardless of the number of items
ordered. In addition to the handling cost, Metro Tech must pay a trucking cost of $500 for each
delivery regardless of the total number of components in the order. Currently, all three items
are being ordered independently using EOQ models. A proposal has been made to combine the
ordering of the three items to save on trucking costs. Analyze the current and the prosed
scenario and show the results below.
