Final answer:
To find the least number of instructors needed to teach guitar lessons to a group of 25 people, divide the total number of students by the maximum number of students per instructor and round up to the nearest whole number.
Step-by-step explanation:
To find the least number of instructors needed to teach guitar lessons to a group of 25 people, we divide the total number of students by the maximum number of students per instructor.
25 students / 2 students per instructor = 12.5 instructors
Since we can't have a fraction of an instructor, we need to round up to the nearest whole number. Therefore, the least number of instructors needed is 13.
The student is asking how to calculate the least number of instructors needed for a group of 25 people who want to sign up for guitar lessons, with each instructor being able to take a maximum of two students. To find the solution, you need to divide the total number of students by the maximum number of students per instructor.
The calculation is as follows: 25 students ÷ 2 students per instructor = 12.5. Because you cannot have half an instructor, you would need to round up to the nearest whole number. Therefore, the least number of instructors needed is 13.
