The Kasibu Cooperative has invested a 145,000 new mechanical grading/sorter
system which is projected to improve throughput and increase revenue by 14,000
per year for five years. The estimated market value of the sorter system at the end
of five years is 5,000. Using the FW method at a MARR of 12%, is this a good
investment?
Question 8
Canada's Wonderland has decided to carry out an analysis to determine when one of its roller coasters should be replaced. The existing roller coaster was purchased 25 years ago for $715,000. The costs of operating and maintaining this ride for a 5-year study period are predicted to be $70,000 in year 1 and would increase by $1,300 each year thereafter (i.e. $71,300 in year 2, $72,600 in year 3, etc.) Canada's Wonderland uses a MARR of 10% for roller coaster projects. (a) If the roller coaster loses value at a rate of 7% per year, what is the salvage value at the end of the study period? (b) What is the EAC for operating & maintenance costs (O&M) after 4 years in the study period? (c) Supposing the salvage value after 2 years in the study period is $100,773, what is the EAC for capital costs after 2 years in the study period? . (d) What is the economic remaining life of the roller coaster (i.e. in the study period)?
A bridge is to be constructed now as part of a new road. Engineers have determined that traffic density on the new road will justify a two-lane road and a bridge at the present time. Because of uncertainty regarding future use of the road, the time at which an extra two lanes will be required is currently being studied.
The two-lane bridge will cost $220,000 and the four-lane bridge, if built initially, will cost $420,000. The future cost of widening a two-lane bridge to four lanes will be an extra $220,000 plus $26,000 for every year that widening is delayed. The MARR used by the highway department is 18% per year. The following estimates have been made of the times at which the four-lane bridge will be required:
