Consider the following two investment alternatives. Determine the range of investment costs for Alternative B (i.e., min. value
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?
(Upload the picture of your complete solutions including the correct cash flow diagram and your conclusion.)
Determine the ERR of the engineering project shown below when the MARR is 189% per year and the reinvestment rate is 15% per year. Express your answer in percent rounded to the nearest hundredths.
