A Boxerville Express commuter train leaves the station every 30 minutes.
When Theo arrives at the station, a woman tells him she has been there for
10 minutes and that she just missed the last train. If the variable t stands for
the amount of time Theo will have to wait, which of the following choices is
the most reasonable value for t?

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
