<human>:  The class plans to take a field trip to the zoo. The cost to rent a school bus is $100. The cost of admission is $10 per student. The teacher is allowed in for free. If the class has a budget of $350, how many students can go on the field trip?
<bot>: How much money is there to pay for the students' admission fees? ** There is $350 - $100 = $<<350-100=250>>250 available to pay for the students' admission fees.
How many students can they bring on the trip? ** This means they can afford to bring $250 / $10 = <<250/10=25>>25 students on the trip.
