Answer:

E. Time, in hours

Explanation:

given data

charges her $50 per hour]

plus a service call fee of $75.

we know that the total cost can be expressed as

y=75+50x------this is the function to represent the situation

where x is the number of hours worked

Hence the input independent variable is x, which is the time she can dedicate for the work
