Question

Sheryl paid a plumber x dollars per hour for a 6-hour job plus $70 for parts. The total charge was $325. Which equation can be used to determine how much the plumber charged per hour?

A. 6x - 70 = 325
B. 6x + 70 = 325
C. (70 + 6)x = 325
D. (70 - 6) x = 325

Answer 1

The correct equation to determine the plumber's hourly charge is B. 6x + 70 = 325, where x represents the hourly rate.

Step-by-step explanation:

The question involves determining the plumber's hourly charge from a total cost for a job that includes both labor and parts. To set up the correct equation, we will let x represent the plumber's hourly rate.

The plumber worked for 6 hours and charged $70 for parts. The total cost of the job was $325. So, if we multiply the plumber's hourly rate by the number of hours worked (6 hours), and add the cost of parts ($70), we should get the total cost:

6x + 70 = 325

This equation represents the total cost as the sum of labor charges and parts cost. Thus, the correct answer is:
B. 6x + 70 = 325
