Calculator solution: CF0 = -3,600,000, CF1 – CF10 =600,000, I = 11; compute NPV = -66,460.79; IRR =

Alternative calculator solution using TVM keys: N = 10, PV = -3,600,000, PMT = 600,000, FV = 0;
compute I/Y = 10.56% = IRR
The investment is not acceptable, because NPV < 0 and IRR < r = 11%.

Note: Students who use the projects’ IRRs to determine which project should be purchased would
choose Project S, because its IRR is 19.01 percent (Calculator solution: CF0 = -16,000, CF1 = 14,000,
CF2 = 6,000, compute IRR = 19.01%); thus, IRRS > IRRT. But, Project S should not be purchased
because its NPV is lower than Project T’s NPV; that is NPVS < NPVT.
