need help with the steps tp this question i have been struggling on: Vancouver Shakespearean Theaters board of directors is considering the replacement of the theaters lighting system. The old system requires two people to operate it, but the new system would require only a single operator. The new lighting system will cost $121,450 and save the theater $25,000 annually for the next eight years.

1. Prepare a table showing the proposed lighting systems net present value for each of the following discount rates: (8%, 12%& 16% only.)

2. Also try calculate Payback and AROR
