Answer: The independent variable = x which represent the the number of hours taken to complete the job.

Step-by-step explanation:

  • Independent variable is the variable on which dependent variable is dependent.

In the given function: y = 50 + 65x, x = Number of hours, y = Total cost of the job.

Here, total  cost of the job depends on the number of hours.

So the independent variable = x which represent the the number of hours taken to complete the job.
