The initial y of a construction ive are shown. Assuming the MARR is 14.5% Initial Cost (s) Revenue (5s per year) Rate of Return (%) -16,000 2,200 2 -3,000 1,400 15.6% 16.7% ) Calculate the Rate of Return of Alternative Z. 2) Using the Incremental ROR Analysis Nothing" is not an option) which alternative should be selected? "Do-

Explanation / Answer

let rate of return be i

so 16000 = 2200/(1+i) + 2200/(1+i)^2 + 2200/(1+i)^3 +.........

16000 = 2200/(1+i) [ 1+1/(1+i) +1/(1+i)^2+.........

when i>1, 1/(1+i) <1 , in that case

then RHS become 2200/(1+i) [1/1-(1/(1+i))] ;

= 2200 *i /(1+i)^2 = 16000

solving i=1.334; so R= 13.6%

the alternative which provides better return should be selected, in this case it is Y
