Answer:
The statements are not provide. However we can find the right one by interpreting the given expression.
In a linear expression we have a independent term, and a dependent term, the first one isn't with the variable, and the second one is with the variable.
So, the independent term represent an initial condition which is constant, and the term with the variable represents the ratio per magnitude.
Therefore, 150 represents the one-time evaluation fee, because is the initial condition for the service. And the term 55x represents the monthly fee for the service where x represents months.
