Final answer:
To calculate the average amount of money spent on admission and lunch per student during a school field trip to the zoo, the combined cost of admission and lunch ($893.12) is divided by the number of students (41), which equals $21.78 spent per student.
Step-by-step explanation:
The question asks us to calculate the average amount of money spent on admission and lunch for each student during a school field trip to the zoo. In total, the school spent $531.91 on admission for 41 students and 2 teachers, and the students spent an additional $361.21 on lunch for just the students.
First, to find the total cost per student, we need to add the admission cost and the lunch cost, then divide by the number of students:
- Calculate the total cost by adding the admission and lunch costs: $531.91 + $361.21 = $893.12.
- Divide the total cost by the number of students: $893.12 ÷ 41 = $21.78.
Therefore, the average amount spent on admission and lunch per student is $21.78.
