Suppose you deposited $ 2,000 four years ago and another $1,000 two years ago in your saving account. If your current account balance shows $5,250 find the interest rate (Rate of Return) on your deposit? In the design of certain industrial facilities, two alternative structures are under consideration. We identify these two alternatives as Plan A and Plan B. Estimates for Plan A and B are: It is desired to compare these alternatives using a minimum attractive rate of return (MARR) of 10%. Make cash flow diagrams of two plans: a) Compare plan A and B by using Annual Equivalent cost method. b) Compare Plan A and B using the Net Present worth method. (For using Present worth method You need to have the same number of service lives for both plans. Consider renewal of plan A for another 5 years for Present worth calculation. c) Find the Capitalized Cost of Plan A and Plan B. (You can find Capitalized Cost by finding Present worth for perpetual service life). For both plans you should assume infinite series of renewals
