The following table shows the CAPM-type relation- ship between a risk index and the required return (RADR) applicable to CBA Company. Risk index Required return (RADR) 0.0 7.0% (risk-free rate, R) 0.2 8.0 0.4 9.0 0.6 10.0 0.8 11.0 1.0 12.0 1.2 13.0 1.4 14.0 1.6 15.0 1.8 16.0 2.0 17.0 Project data are as follows: Project A Project B Initial investment (CF) -$15,000 -$20,000 Project life 3 years 3 years $10,000 Annual cash inflow (CF) $7,000 0.4 Risk index 1.8 a. Ignoring any differences in risk and assuming that the firm's cost of capital is 10%, calculate the net present value (NPV) of each project. b.
