The NPVs of Projects R and S are b. The annualized NPV of Project R is c. The annualized NPV of Project Sis Annualized NPV = NPV of project / PVIFA (ni) For project R: ANPV = 18274.25 / PVIFA (4,14%) = 18274.25 2.91371 6271.81 For project S: ANPV = 10636.50 / PVIFA (n,i) = 10636.50 / PVIFA (2,14%) = 10636.50 /1.64666 = 6459.44 MY QUESTION IS HOW DID YOU CALCULATE PVIFA AND THE RED MARK NUMBERS
