You are faced with a decision on an investment proposal. Specifically, the estimated additional income from the investment is $125,000 per year; the investment cost is $400,000; and the first year estimated expense of $20,000 and will increase a rate of 5% per year. Assume an 8-year analysis period, no salvage value, and MARR = 15% per year.
a. Calculate the PW and FW of this proposal?
b. What is the ERR ( Ԑ=MARR) of this proposal?
c. What is the Simple and Discounted payback?
include the cash flow diagram and conclusion
As supervisor of a facilities engineering department, you consider mobile cranes to be critical equipment. The purchase of a new, medium-sized truck-mounted crane is being evaluated. The economic estimates for the two best alternatives are shown in the following table. MARR is at 15% per year. You can use the assumption of repeatability in this case.
Show that the same selection is made for the following methods:a. RORAI method
b. AWC method
c. PW method
A tunnel to transport water initially cost
$1,000,000 and has expected maintenance
costs that will occur in a 6-year cycle as
shown below, assume MARR is 10% per year.
End of Year:

The first plan calls for an initial investment of $500,000, with expenses of $20,000 per year for the first 20 years and $30,000 per year thereafter. It also requires an expenditure of $200,000 20 years after the initial investment, and this will repeat every 20 years thereafter. The second plan has an initial investment of $700,000 followed by a single (one time) investment of $300,000 30 years later. It will incur annual expenses of $10,000 forever.
