A factory manager is planning for the manufacture of plywood to be sold overseas. The fixed cost of operation is estimated at $800,000 per month while the variable cost is $155 per thousand board feet of plywood. The selling price will depend on how much will be produced and sold and is determined by the relationship, price per thousand board feet, p = $600 – 0.05D, where D is the amount produced and sold in thousands of board feet. Determine the range of profitable production. For profitable production, production must be at least housands of board feet per month, but not more than . (Round to the nearest unit.)

Please read the project 2 description, then write down the solution strategy answer should be 100 words only The project 2 descriptions is shown as follows: There are three tanks as shown in Figure 1. Tank T1 initially contains 40 gals of water in which 16.98 lb of salt is dissolved. Tank T2 initially contains 40 gals of water and 3.92 lb of salt. Tank T3 initially contains 40 gals of water and 7.13 lb of salt. The inflow into T1 is 2 gal/min pure water from the outside and 2 gal/min brine from T2. The outflow from T1 to T2 is 4 gal/min.The inflow into T2 is 4 gal/min from T1 and 2 gal/min from T3. The outflow from T2 to T1 is 2 gal/min and from T2 to T3 is 4 gal/min. The inflow into T3 is 4 gal/min from T2. The outflow from T3 to T2 is 2 gal/min and from T3 to outside is 2 gal/min, as shown in the figure. The mixtures are kept uniform by stirring. Find and plot the salt contents y1(t), y2(t), and y3(t) in T1, T2, and T3, respectively
engineering economics course QUESTION: Freeport McMoran purchased two model MTVS peristaltic pumps (to inject sulfuric acid and King Lee antiscalant) for use at its nanofiltration water conditioning plant. The cost of the pumps was $950 each. If the chemical cost is $11 per day, determine the equivalent cost per month at an interest rate of 12% per year, compounded monthly. Assume 30 days per month and a 3-year pump life.
