A school is allowing its seniors to write proposals for their senior trip. Group A Submits an idea for attending a theme park. It would cost $200 to rent a bus, $5.50 per student for food and $35.75 per student for tickets. Group B submits a proposal to go to the beach and aquarium. For this trip it would cost $350 for the bus, $7.25 per student for food, and the aquarium is $4.00 per student. How many students would need to attend for the prices of the two trips to be the same?
