A group of students is taking a CPR course. The total cost for the course is $275. The room in which the course will b including the instructor. What is the minimum number of students needed to take the course so that the cost per stud (1 point)
A) 11
B) 17
C) 18
D) 19
A) 11
Explanation:
Let x be the number of students needed to take the course.
The cost per student is given by $275 divided by x.
To find the minimum number of students needed to make the cost per student less than or equal to $19, we set up the following inequality:
275/x ≤ 19
x ≥ 275/19
x ≥ 14.47368421
The smallest integer greater than or equal to 14.47368421 is 15.
Therefore, the minimum number of students needed to take the course so that the cost per student is less than or equal to $19 is 15 or more, so the answer is A) 11.
