VGHC, humanitarian aid service in the Sub-Saharan Africa, operates its laboratory on-site. The lab maintains an inventory of test kits for a variety of procedures. VGHC uses 780 A1C kits each year. Ordering costs are $15 and holding costs are $3 per kit per year. The new price list indicates that orders of fewer than 73 kits will cost $60 per kit, 73 through 144 kits will cost $56 per kit, and orders of more than 144 kits will cost $53 per kit.
Determine the optimal order quantity and the total cost.
Joint Products Choi Company manufactures two skin care lotions, Smooth Skin and Silken Skin,from a joint process. The joint costs incurred are $420,000 for a standard production run that generates 180,000 pints of Smooth Skin and 120,000 pints of Silken Skin. Smooth Skin sells for $2.40 perpint, while Silken Skin sells for $3.90 per pint.Required1. Assuming that both products are sold at the split-off point, how much of the joint cost of each production run is allocated to Smooth Skin using the relative sales value method?2. If no separable costs are incurred after the split-off point, how much of the joint cost of each productionrun is allocated to Silken Skin using the physical measure method method?3. If separable processing costs beyond the split-off point are $1.40 per pint for Smooth Skin and $0.90 perpint for Silken Skin, how much of the joint cost of each production run is allocated to Silken Skin usinga net realizable value method?4. If separable processing costs beyond the…

- 30) XYZ Company The XYZ Company uses 175 handles per day. The company operates 300 days per year. It costs $2.00 to carry one handle in inventory for one year. When handle inventory is low, an order is sent to the fabrication department to manufacture more handles. Fabrication can produce handles at a rate of 1500 per day and send the handles over to assembly while production is in progress. The setup for each production run costs $500. Assume the XYZ company orders 9,000 handles at a time (not necessarily the economic order quantity). The order receipt period = _____ days.
