Problem:A diagnostics laboratory is considering one of the following microscopes with digital recording and pattern detection software:
Option A Option B Options C
Cost $20,000 $30,000 $15,000
Savings $1,199 $2,199 $1,000
IRR 6% 9% 7%
Each machine will have a 20-year life with no salvage value. There is a lot of debate within the company as to whether these devices are really going to last long, but they assume MARR of 10% as reasonable.

What is MARR?
