Project A has an initial cost of $75,000 and annual cash flows of $33,000 for three years. Project B costs $60,000 and has cash flows of $25,000, $30,000, and $25,000 for Years 1 to 3, respectively. Projects A and B are mutually exclusive. The incremental IRR is and if the required rate is higher than the crossover rate then Project should be accepted.

Six years ago, an 80-kw diesel electric set cost $160,000. the cost index for this class of equipment six years ago was 187 and is now 194. the cost-capacity factor is 0.6. the plant engineering staff is considering a 120-kw unit of the same general design to power a small isolated plant. assume we want to add a precompressor, which (when isolated and estimated separately) currently costs $13291. determine the total cost of the 120-kw unit.
