Question

A plumber has estimated that a job will take at least two hours to complete, and the parts for the job cost $36. The plumber charges $35 an hour. What is the minimum amount he will charge his customer?

A) $106
B) $106
C) $141
D) $141

Answer 1

The minimum amount the plumber will charge his customer is A)$106, which is calculated by adding the cost of labor to the cost of parts.

Step-by-step explanation:

To find the minimum amount the plumber will charge his customer, we need to calculate the cost of labor and add it to the cost of parts. The labor cost is calculated by multiplying the number of hours (at least 2 hours) by the hourly rate ($35/hour). Therefore, the labor cost is 2 hours x $35/hour = $70. Adding this to the cost of parts ($36), the minimum amount the plumber will charge his customer is $70 + $36 = $106. Therefore, option A) $106 is the correct answer.
