Final answer:
To determine the per-student cost for the field trip to the zoo, the total cost for passes and lunches ($1015.56) was divided by the number of students (28), resulting in a cost of $36.27 per student.
Step-by-step explanation:
To calculate how much money was spent on a pass and lunch for each student, we first need to add the total amounts spent on passes and lunches and then divide that sum by the number of students. The school spent $754.88 on passes for students and teachers and $260.68 on lunch for the students.
Since the passes were for both students and teachers, we should only consider the students when finding the per-student cost. Therefore, we only divide the total cost by the number of students, which is 28.
First, we find the total cost spent on students alone for passes and lunch:
- Total cost for passes and lunch: $754.88 (passes) + $260.68 (lunch) = $1015.56
- Cost per student: $1015.56 / 28 students = $36.27 per student (rounded to two decimal places)
So, each student's pass and lunch cost the school $36.27.
