Answer
True.
Work Step by Step
Let the number of persons $=x$.
Cost of limousine $=\$300$.
Cost per ticket $=\$25$.
Total cost per ticket $=25x$.
Total cost: $=300+25x$.
For the cost per person divide the total cost by the number of persons.
The function is
$f(x)=\frac{300+25x}{x}$
Hence, the given rational function is correct.
