You are to evaluate two mutually exclusive business projects with expected cash flows described below. Assuming a 10% weighted average cost of capital (WACC), calculate NPV and IRR for each project and determine which project to accept.

(1) Project A's NPV (3 points): 

(2) Project A's IRR (3 points): 

(3) Project B's NPV (3 points): 

(4) Project B's IRR (3 points): 

(5) Which project should be chosen? (4 points)

2 3 4 Project A -100 WACC=10 | 50 + 40 10 30 10 Project B 1 2 WACC=10 + 3 + -100 10 30 40 68
