Isabelle Abiassi operates a popular summer camp for elementary school children. Projections for the current year are as follows: The camp's weighted-average cost of capital is 10%, and Isabelle requires that all new investments generate a return on investment of at least 15%. The camp's current tax rate is 25%. At last week's advisory board meeting, Isabelle told the board that she had up to $50,000 to invest in new facilities at the camp and asked them to recommend some projects. Today the board's president presented Isabelle with the following list of three potential investments to improve the camp facilities. Calculate the return on investment, residual income, and economic value added for each of the three projects. (Enter negative amounts using either a negative sign preceding the number e.g. -45 or parentheses e.g. (45). Round Economic Value Added answer to 2 decimal places, e.g. 15.25 & all other answers to 0 decimal places, e.g.15 or 15%.)
