a. if you plotted the NPV profiles, what would be the "crossover rate" in the graph? (note you are not asked to actually plot NPV profiles) . please make sure your supporting work shows either algebra or financial calculator input limited to the five financial time value of money keys (N, I or I/YR depending on calculator model, PV, PMT, and FV) showing excel input or output will not earn credit

b.
