The total amount needed for the equipment is $350.
The number of students on the team is x students.
To find the amount required per student, consider that each student will pay equally. Therefore, the amount can be gotten by division.
Hence, the amount per student can be gotten as:
[tex]\Rightarrow\frac{\text{Amount}}{\text{Number of Students}}[/tex]
This then becomes, by substitution:
[tex]=\frac{350}{x}[/tex]
The correct answer is OPTION C.
