Consider two options for buying a piece of equipment:

In Option A, you buy the piece of equipment for $120K and can sell it in 10 years for $30K

In Option B, you buy the piece of equipment for $100K, can sell it in 10 years for $20K but have to pay $10K in year 5 for planned maintenance.

In either case, you earn $30K each year when you use the piece of equipment. Based on IRR, which option is preferable?
