Consider the two mutually exclusive projects in the table below. The salvage value for each project at the end of each year is also presented in the table below. If the planning period is indefinite which project would you chose based on the net present worth criterion at MARR of 13% per year? (All amounts are in SR) NOTE: Both projects B1 and B2 will be available (or can be repeated) with the same costs and salvage values for an indefinite period
