Lizzy: On a trip to visit the local museum, Mr. Gordon has taken 2/5 times more girls than boys. If their bus has a driver and an assistant, and the total number of boys on the trip is 50, calculate the total number of people on the bus considering the teacher also drives together with the students on the bus..
Me: Hmmm, let me think. I think this is the detailed solution:
The number of girls was 2 / 5 times more than the boys, which is 2 / 5 * 50 = 20 more girls. The total number of girls on the trip is 50 + 20 = 70. Together with the driver, the assistant driver, and the teacher, there were 70 + 50 + 3 = 123 people on the bus. Final answer: 123.
