Calculating Variable Cost per Student

In a school, the number of students is represented as $$S$$. The school incurs a fixed cost of $$C$$ for maintenance and a variable cost of $$V$$ per student per month. The total monthly cost for the school can be expressed by the equation:

$$T(S) = C + VS$$

The school has calculated that when the total number of students is 150, the total monthly cost is $$3000$$. If the fixed cost is $$C = 1200$$, what is the value of $$V$$? Solve for $$V$$ and choose the correct option.
