Consider the following set of independent investment projects: 0 (a) For a MARR of 10%, compute the net present worth for each project, and determine the acceptability of each project. (b) For a MARR of 10%, compute the net future worth of each project at the end of each project period, and determine the acceptability of each project. (c) Compute the future worth of each project at the end of six years with variable MARRs as follows: 10% for n = 0 to n - 3 and 15% for n 4 to n = 6
