Suppose that a plumbing repair bill, not including tax, was $120. This included $25 for parts and an amount for 2 hours of labor. Find the hourly rate that was charged for labor.
2x = 120 - 25
Solve for x.
2x=120-25
2x=95
95/2
x=47.50
To find the hourly rate charged for labor, we need to divide the total labor cost by the number of hours worked.
Given that the total bill was $120 and it included $25 for parts, we can find the labor cost by subtracting the cost of parts from the total bill:
Labor cost = Total bill - Cost of parts
Labor cost = $120 - $25
Labor cost = $95
We also know that the labor cost includes 2 hours of work.
To find the hourly rate, we divide the labor cost by the number of hours:
Hourly rate = Labor cost / Number of hours
Hourly rate = $95 / 2
Hourly rate = $47.50
Therefore, the hourly rate that was charged for labor is $47.50.
