Ridgley Custom Metal Products (RCMP) must purchase a new tube bender. RCMP's MARR is 12 percent. RCMP can forecast demand for its products for only 4 years in advance. The salvage value after 4 years is $50,000 for model T, $85,000 for model A and $75,000 for model X. Using the study period method, which of the three alternatives is best? Salvage Value $50.000 Yearly Net Savings $55.000 $50.000 $65.000 Model First Cost Economic Life $100,000 $140,000 $190,000 4 years 4 years A $85,000 $75,000 4 years Click the icon to view the table of compound interest factors for discrete compounding periods when i= 12%.

8. A school is creating class schedules for its students. The students submit their requested courses and then a program will be designed to find the optimal schedule for all students. The school has determined that finding the absolute best schedule cannot be solved in a reasonablo time. Instead they have decided to use a simpler algorithm that produces a good but non-optimal schedule in a more reasonable amount of time. Which principle does this decision best demonstrate? O A Unreasonable algorithms may sometimes also be undecidable O B. Heuristics can be used to solve some problems for which no reasonable algorithm exsts O C. efficiency Two algorithms that solve the same problem must also have the same O B. Approximate solutions are often identical to optimal solutions
Assuming all Ghanaianswho are at least 18 years can choose between going to school or learning a trade. GHC 100is invested every month fora person who chooses to go to schoolby the government till the person attains age 30 years provided he/she completes university.If he/shedoes not completeuniversity, the payment is stopped at the time he/she exited. If the person chooses to learn atrade, the government pays GHC 2000 as apprentice fee to the madam or master who will take the person as an apprentice, and invest GHC 70 a month till age 30 years. If the person does not complete the apprenticeship, the payment is stopped at the time he/she exited. Remember that persons who are less than 18 years or 30years and above do NOT qualify to enroll on this program.You are to write ac++ program for the above scenario. Your program should a)request a person’s name, age, what he/she wants to do (go to school or learn a trade), time of exit if anyand disqualify the person if he/she does not meet…
