Final answer:
The equation that expresses the total cost in terms of the number of hours required to complete the job is Total Cost = 32 * Number of Hours + 31.50.
Step-by-step explanation:
To find the equation that expresses the total cost in terms of the number of hours required to complete the job, we can use the formula:
Total Cost = Hourly Rate * Number of Hours + One-time Charge
In this case, the hourly rate is $32 and the one-time charge is $31.50. So the equation is:
Total Cost = 32 * Number of Hours + 31.50
