Answer:the number of hours of labour that was needed to complete the job is 4

Step-by-step explanation:

On the final bill, Ngoc was charged a total of $649. $365 was listed for parts and the rest for labor. This means that the total cost of labour would be the total charge - the amount listed for parts.

649 - 365 = $284

If the hourly rate for labor was $71, it means that the number of hours that the plumber worked would be

284/71 = 4 hours
