School guidelines require that there must be at least 2 chaperone for every 25 students going on a school trip.How many chaperones must there be 80 students?
For 80 students, there must be at least 2 chaperones for every 25 students.
We can find the number of groups of 25 students in 80 by dividing 80 by 25.
80 / 25 = 3 remainder 5
This means that there are 3 groups of 25 students and an additional 5 students.
Since each group of 25 students requires 2 chaperones, we need 3 groups * 2 chaperones = <<3*2=6>>6 chaperones.
Therefore, for 80 students, there must be at least 6 chaperones.
To determine the number of chaperones required for 80 students, we need to divide the number of students by 25 and then multiply the result by 2.
Number of chaperones = (Number of students / 25) * 2
Number of chaperones = (80 / 25) * 2
Number of chaperones = 3.2 * 2
Number of chaperones = 6.4
Since we cannot have a fractional number of chaperones, we round up to the nearest whole number.
Therefore, there must be at least 7 chaperones for 80 students.
To determine the number of chaperones required for 80 students, we need to apply the guideline of having at least 2 chaperones for every 25 students.
Step 1: Calculate the number of sets of 25 students within the group of 80 students.
- Divide the total number of students (80) by the number of students per set (25):
80 ÷ 25 = 3 with a remainder of 5
Step 2: Determine the number of chaperones for whole sets of 25 students.
- Multiply the number of sets (3) by the number of chaperones per set (2):
3 × 2 = 6 chaperones
Step 3: Determine the number of additional chaperones required for the remaining students.
- Since there are 5 remaining students, we need an additional set of 2 chaperones according to the guideline:
2 chaperones
Step 4: Calculate the total number of chaperones required.
- Add the chaperones for the whole sets and the additional chaperones for the remaining students:
6 + 2 = 8 chaperones
Therefore, for a group of 80 students, there must be at least 8 chaperones.
