I hope i did all of that correctly. Can someone check my math on the derivatives...and is there anyway to simplify them? Now i must show that the population P reaches half the limiting population M, when P\'\'=0 [ie when P\'\'=0 P=M/2] what should i do here? Solution You could have tried it in another way. 1/P = (1/M) + ((1/P0) - (1/M)) eMR(t0-t) Now differentiating it woul;d be easier.

I must have the formula / calculation view from the spreadsheet to solve the questions. So instead of just seeing that cell A25 is $XX.00, it should show the formula i.e. =A1*B2+A1. Thank you! Rio Claro, Inc. (RCI) is in the business of transporting cargo between ports in California and Washington. Its fleet includes a small dry-cargo vessel, theMaracas. The Maracas is 25 years old and badly in need of an overhaul. It is March 2016, and Michael John, the finance director, has just been presented with a proposal that would require the one-time expenditures shown below in Table 1. If the proposal is accepted, these expenditures will be made in the next few days. Mr. John believes that all these outlays could be depreciated for tax purposes in the seven-year MACRS class (see Table 2 below for rates). Overhaul of theMaracas will begin as soon as the expenditures in Table1 are made, but the vessel will be out of service for several months. The overhauled vessel would resume commercial service in one year. RCI’s chief engineer’s estimates of the post-overhaul operating costs are in Table 3. In addition to the overhaul described above, the chief engineer suggests installation of a brand- new engine and control system. Installation of this new engine would cost an extra $600,000 (This additional outlay would also qualify for tax depreciation in the seven-year MACRS class.). However, if the additional equipment is installed, it would result in reduced fuel, labor, and maintenance costs as shown in Table 4. The operating cost estimates in Tables 3 and 4 are current for March 2016. However, these costs will increase with inflation, which is forecasted at 1.25% a year. Depreciation and operating costs attributable to the overhaul of theMaracaswill begin one year after the vessel is put back into commercial service. The revenues from operating the vessel will be the same for both types of overhaul. Even with the proposed overhaul, the Maracas cannot continue forever. After the overhaul, its remaining useful life is estimated to be only 12 years. Its salvage value when finally taken out of service will be trivial. Thus, Mr. John feels it is unwise to proceed without also considering the purchase of a new vessel. Racette & Sons (R&S), a Colorado shipyard, has approached RCI with a design incorporating a Kort nozzle, extensively automated navigation and power control systems, and much more comfortable accommodations for the crew. R&S is offering the new vessel for a fixed price of $3,000,000, payable half immediately and half on delivery in one year. Estimated annual operating costs of the new vessel are in Table 5. The operating cost estimates in the table are current for March 2016, but will increase with inflation. The crew would require additional training to handle the new vessel’s more complex and sophisticated equipment. Training would result in a one-time cost of $50,000 payable one year following delivery of the new vessel. This cost is tax deductib.
