A group of science students went on a field trip. They took 9 vans and 10 buses. There were 8 people in each van and 27 people on each bus. How many people went on the field trip? Think carefully first, then make a decision:
The vans held 9 vans * 8 people = 72 people. The buses held 10 buses * 27 people = 270 people. The total number of people on the field trip is 72 + 270 = 342 people. So, the answer is 342.
