3. Black Ridge Refining extracts minerals from ore mined at two different sites in Utah. Each ton of ore type 1 contains 15% copper, 20% zinc and 15% magnesium. Each ton of ore type 2 contains 25% copper, 25% zinc and 10% magnesium. Ore type 1 costs $90 per ton and ore type 2 costs $120 per ton. Black Ridge would like to buy enough ore to extract at least 8 tons of copper, 6 tons of zinc, and 5 tons of magnesium in the least costly manner. a. Formulate a spreadsheet model and use Solver to solve this LP problem. Copy and paste model below. a. Based on the sensitivity report, how much would it cost the company to get one more ton of copper

Yowell company granted a sales discount of $360 to a customer when it collected the amount due on account. yowell uses the perpetual inventory system. which of the following answers reflects the effects on the financial statements of only the discount? assets = liab. + equity rev. − exp. = net inc. cash flow a. (360 ) = na + (360 ) (360 ) − na = (360 ) (360 ) oa b. na = (360 ) + 360 360 − na = 360 na c. (360 ) = na + (360 ) (360 ) − na = (360 ) na d. na = (360 ) + 360 360 − na = 360 na

Zachary company produces commercial gardening equipment. since production is highly automated, the company allocates its overhead costs to product lines using activity-based costing. the costs and cost drivers associated with the four overhead activity cost pools follow: activities unit level batch level product level facility level cost $ 64,800 $ 27,730 $ 15,000 $ 154,000 cost driver 2,400 labor hrs. 47 setups percentage of use 11,000 units production of 780 sets of cutting shears, one of the company’s 20 products, took 240 labor hours and 7 setups and consumed 15 percent of the product-sustaining activities. required: (a) had the company used labor hours as a company wide allocation base, how much overhead would it have allocated to the cutting shears? (b) how much overhead is allocated to the cutting shears using activity-based costing? (c) compute the overhead cost per unit for cutting shears first using activity-based costing and then using direct labor hours for allocation if 780 units are produced. if direct product costs are $150 and the product is priced at 30 percent above cost for what price would the product sell under each allocation system? (d) assuming that activity-based costing provides a more accurate estimate of cost, indicate whether the cutting shears would be over- or underpriced if direct labor hours are used as an allocation base. explain how over-or undercosting can affect vaulker's profitability. (e) comment on the validity of using the allocated facility-level cost in the pricing decision. should other costs be considered in a cost- plus pricing decision? if so, which ones? what costs would you include if you were trying to decide whether to accept a special order?

When a company produces and sells x thousand units per week, its total weekly profit is p thousand dollars, where upper p equals startfraction 800 x over 100 plus x squared endfraction . the production level at t weeks from the present is x equals 4 plus 2 t. find the marginal profit, startfraction dp over dx endfraction and the time rate of change of profit, startfraction dp over dt endfraction . how fast (with respect of time) are profits changing when tequals8?
