Compare average annual cost = (purchase price)/years + yearly maintenance.

For Bike A: cost = 270/n + 36.
For Bike B: cost = 360/n + 20.

At n = 5: A = 270/5 + 36 = 90, B = 360/5 + 20 = 92 → A is better.
At n = 6: A = 270/6 + 36 = 81, B = 360/6 + 20 = 80 → B is better.

So: "Bike A is the better choice if Greg plans on owning the bike for 5 years. Bike B is the better choice if Greg plans on owning the bike for 6 years."
