As it is not mentioned, how many students and teachers are going, so Option B and option E can be the answers.
Explanation for option B:
B = Tickets cost $52.00 each, and there are 25 students and 2 teachers going on the field trip.
Total Cost = 52(25+2)
This means that a total of 27(25+2) people are going and each ticket costs $52.
Explanation for option E :
E = Tickets cost $25 and each person must contribute $2 for the bus. There are 52 people going on the trip.
This means a total contribution of $27 is needed from all the 52 people who are going.
So, these are the best possible answers.
