Answer:
$1.33 per student
Step-by-step explanation:
Mr. Luu spent 15.99 on new flashlights.
Total number of students = 12
We need to find the unit cost per student. It can be calculated by dividing the total cost and the total number of students.
[tex]C=\dfrac{15.99}{12}\\\\C=1.33[/tex]
So, the required cost per student is 1.33.
