Project Cash Flows
n A B C
0 -$100 -$100 $100
1 $50 $40 -$40
2 $50 $40 -$40

1. For a MARR of 10%, compute the net present worth for each project, and determine the acceptability of each project.
2. 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.
3. 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.

Quick calculate the roi dollar amount and percentage for these example investments. a. you invest $50 in a government bond that says you can redeem it a year later for $55. use the instructions in lesson 3 to calculate the roi dollar amount and percentage. (3.0 points) tip: subtract the initial investment from the total return to get the roi dollar amount. then divide the roi dollar amount by the initial investment, and multiply that number by 100 to get the percentage. b. you invest $200 in stocks and sell them one year later for $230. use the instructions in lesson 3 to calculate the roi dollar amount and percentage. (3.0 points) tip: subtract the initial investment from the total return to get the roi dollar amount. then divide the roi dollar amount by the initial investment, and multiply that number by 100 to get the percentage.
