Q: A one-way ticket costs $2. A 30-day pass costs $50. What's the minimum number of rides you will need to take every month so that the 30-day pass is strictly cheaper per ride?
A: For the 30 - day pass to be cheaper, then the average fare should be cheaper than the $2 one - way ticket. If the 30 - day pass costs $50, then I should take at least $50 / $2 = 25 rides to pay the same as a one - way ticket. However, given that we want the 30 - day pass per ride to be strictly cheaper we should ride at least 25 + 1 = 26 times. The answer is 26.
