NO.PZ2018101501000035 Company M is investing in a four-yeproject, relevant information is shown in the following table. The company is in the 25% tbracket. The weighteaverage cost of capitanthe cost of equity is 10% an15%, respectively. What`s the resiincome in the first year? 3836.15 6184.55 6676.10 A is correct. 考点Other Valuation Mols 解析根据公式RIt = NIt - Re × Bt-1 RI1 = 12,356 – 0.15 × (80,000 - 23,201) = 3836.15 Bt-1 为什么不是80,000？
