A 29.2 mL solution of HBr (a strong acid) of unknown concentration was titrated using 0.2099 mol L-1 NaOH using phenolphthalein as a pH indicator. At the moment when the solution turned a consistent light pink colour, the burette volume read 25.98 mL. The initial burette reading before the experiment was 5.36 mL.

Risk-adjusted discount rates: Basic Country Wallpapers is considering investing in one of three mutually exclusive projects. E, F, and G. The firm's cost of capital, r, is 15%, and the risk-free rate Rf, is 10%. The firm has gathered the basic cash flow and risk index data for each project as shown in the following table. Project (j) E F G Int. Investment (CF0) -$15,000 -$11,000 -$19,000 Year (t) Cash Inflows (CF0) 1 $6,000 $6,000 $4,000 2 $6,000 $4,000 $6,000 3 $6,000 $5,000 $8,000 4 $6,000 $2,000 $12,000 Risk Index (RIj) $1.80 $1 $0.60 Question A Find the net present value (NPV) of each project, using the firm's cost of capital. Which project is preferred in this situation? Question B The firm uses the following equation to determine the risk-adjusted discount rate RADRj, for each project j: RADRj = Rf + [RIj x (r-RF)] where Rf = risk free rate return RIj = risk index for project j r = cost of capital Substitute each project's risk index into this equation to determine its RADR. Question C Use the RADR for each project to determine its risk-adjusted NPV. Which project is preferable in this situation? Question D Compare and discuss your findings in parts A and C. Which project do you recommend that the firm accept?
