ChemLabs uses raw materials I and II to produce two domestic cleaning solutions, A and B. The daily availabilities of raw materials I and II are 150 and 145 units, respectively. One unit of solution A consumes 0.5 unit of raw material I and 0.6 unit of raw material II. One unit of solution B uses 0.5 unit of raw material I and 0.4 unit of raw material II. The profits per unit of solutions A and B are $8 and $10, respectively. The daily demand for solution A lies between 30 and 150 units, and that for solution B between 40 and 200 units. Find the optimal production amounts of A and B.
Machine A has a price of $60,000, annual operating cost of $24,000, and life of 5 years. Machine B has a price of $120,000, annual operating cost of $12,000, and life of 10 years. At MARR=10% per year, use EAC and PW to choose the better machine. (a) Using EAC, which machine would you choose? (b) Using PW, which machine would you choose?
Subject: Engineering Economy Topic: Selections in the Present Economy The monthly demand for ice cans being manufactured by Mr. Cruz is 3,200 pieces. With a manually operated guillotine, the unit cutting cost is P25.00. An electrically operated hydraulic guillotine was offered to Mr. Cruz at a price of P275,000 and which will cut by 30% the unit cutting Disregarding the cost of money, how many months will Mr. Cruz be able to recover the cost of the machine if he decides to buy now?
The potassium industry is perfectly competitive. Firms act as price takers and each firm in the industryoperates only one plant. The following table shows data on incumbent plants in the potassium industry:AverageUnitVariableCost AnnualFixedCosts(millionsper year) Requiredinvestmentto constructnew plant(millions) Salvagevalue ofplantCapacity ofa plant(million tonsper year) Numberofplants $4 per ton $6 $70 $0 1 40 Also: Average variable cost is constant for any output up to full capacity operation. Firms have a cost of capital of 10 percent. All new plants that might be built would be identical to existing plants Market demand is given by the equation, Q = 160 – 5P, where the price P is measured in dollarsper ton and quantity Q is measured in millions of tons. What are the entry price and long-run equilibrium in this industry?
