A swim club is designing a new pool to replace its old pool. The new pool would need to last
for 10 years since the club is planning on relocating after 10 years. A concrete shell would cost
$85,000 and last for all 10 years. Another option is to install a vinyl liner that would cost only
$70,000 to install. However, the vinyl is not guaranteed to last for all 10 years, and it has a 40%
chance of breaking down. Repair of the vinyl would cost $40,000 and would extend the life of
the vinyl liner to the 10-year mark. If both options are acceptable to the swim club, which one
minimizes cost? Support your answer with drawing a decision tree and provide your calculation.
A rural cooperative purchased a trencher at a cost of P230,500.00. It is estimated that the trencher will have a salvage value of P25,000.00 after digging 300,000 meters of irrigation canals. Determine the book value of the trencher after two years, if it was used to dig 50,000 meters on the first year and 75,000 meters on the second year. (Ans. P144,875.00)
An injection molding system has a first cost of $90,000, and an annual operating cost of
$42,000 in year 1, increasing by $5000 per year thereafter. The salvage value of the system is
30,000 if you sell after 1 year of use. The salvage value decreases by $5,000 each year
thereafter. The maximum useful life of the machine is 4 years. Using a MARR of 20% per
year, determine the ESL and the corresponding Equivalent Annual Cost of the system.

- A product engineer has developed the following equation for the cost of a system component: C = (10P)2, where is the cost in dollars and Pis the probability that the component will operate as expected. The system is composed of two identical components, both of which must operate for the system to operate. The engineer can spend $173 for the two components. To the nearest two decimal places, what is the largest component probability that can be achieved?arrow_forwardYour answer is partially correct. An independent contractor for a transportation company needs to determine whether she should upgrade the vehicle she currently owns or trade her vehicle in to lease a new vehicle. If she keeps her vehicle, she will need to invest in immediate upgrades that cost $5,200 and it will cost $1,300 per year to operate at the end of year that follows. She will keep the vehicle for 5 years; at the end of this period, the upgraded vehicle will have a salvage value of $3,800. Alternatively, she could trade in her vehicle to lease a new vehicle. She estimates that her current vehicle has a trade-in value of $9,800 and that there will be $4,100 due at lease signing. She further estimates that it will cost $2,900 per year to lease and operate the vehicle. The independent contractor's MARR is 11%.

Meg Jones, the CEO of Ajax Computer Company, and Brad Smith, its Director of Operations, had been discussing how to increase the firm’s production of the company’s flagship XR58. The XR58 was particularly important because it sold 12,500 of them in the most recent year for $950, at a gross margin of 55%. After a lot of discussion, they decided to pursue an incentive system designed to increase production by 12% in the next year. After Brad discussed this possible incentive with the production team, the team determined that it could increase production by this amount without adding any more people or equipment. They believed they could accomplish this improvement primarily through process redesign. To incent them to do the hard work of process improvement, Brad told the team that it would receive 25% of the increased profits if it met the new production goal. For this team of 20 people, this would mean an additional compensation of _________ for each team member, on average, for…arrow_forward
