Due: 13FEB2024, 11:59pm 1. Consider the project cash flows shown. Compute the equivalent annual worth of each project with MARR = 15% and determine acceptability of each. 2. Consider the cash flows below and compute the equivalent annual worth at i=15%.
3. The repeating cash flows for a certain project are as shown. Find the equivalent annual worth for this project at I = 10% and determine the acceptability of the project. 4. You are considering purchasing a dump truck. The truck will cost $75,000 and have operating and maintenance costs that start at $18,000 the first year and increases by $2,000 per year. Assume that the salvage value at the end of five years is $22,000 and interest rate is 10%. What is the equivalent annual cost of owning and operating the truck? 5. The Geo-Star Manufacturing Company is considering a new investment in a punch-press machine that will cost $100,000 and has an annual maintenance cost of $10,000. There is also an additional overhauling cost of $20,000 for the equipment once every four years. Assuming that this equipment will last infinitely under these conditions, what is the capitalized equivalent cost of this investment at an interest rate of 10%? 6. An industrial firm is considering purchasing several programmable controllers and automating the company’s manufacturing operations. It is estimated that the equipment will initially cost $120,000, and the labor to install it will cost $25,000. A service contract to maintain the equipment will cost $5,000 per year. Trained service personnel will have to be hired at an annual salary of $50,000. Also estimated is an approximate $10,000 annual income-tax savings (cash inflow). How much will this investment in equipment and services have to increase the annual revenues after taxes in order to break even? The equipment is estimated to have an operating life of 10 years with no salvage value (because of obsolescence). The firm’s MARR is 12% 7. A company is currently paying its employees $0.56 per mile to drive their own cars on company business. The company is considering supplying employees with cars, which would involve purchasing at $25,000 with an estimated three-year life, a net salvage value of $8,000, taxes and insurance at a cost of $1,200 per year, and operating and maintenance expenses of $0.30 per mile. If the interest rate is 10% and the company anticipates an employee’s annual travel to be 30,000 miles, what is the equivalent cost per mile (neglecting income taxes)?
8. A city has decided to build a softball complex, and the city council has already voted to fund the project at the level of $800,000 (initial capital investment). The city engineer has collected the following financial information for the complex project: Annual upkeep costs: $120,000 Annual utility costs: $13,000 Renovation costs: $50,000 for every five years Annual team user fees (revenues): $32,000 Useful life: Infinite Interest rate: 8% If the city can expect 20,000 visitors to the complex each year, what should be the minimum ticket price per person so that the city can break even? 9. An industrial firm can purchase a special machine for $70,000. A down payment of $5,000 is required, and the unpaid balance can be paid off in five equal year-end installments at 9% interest. As an alternative, the machine can be purchased for $66,000 in cash. If the firm’s MARR is 12%, use the annual equivalent method to determine which alternative should be accepted. 10. The cash flows shown represent the potential annual savings associated with two different types of production processes, each of which requires an investment of $40,000. Assume an interest rate of 12%. a. Determine the equivalent annual savings for each process. b. Determine the hourly savings for each process if it will be in operation of 3,000 hours per year. c. Which process should be selected?
