Answer:
The BJ Electrical Company
The BJ Electrical Company should hire:
8 master electricians and
22 apprentices
in order to accomplish the project and still meet the contract safety requirements.
Step-by-step explanation:
Number of workers needed = 30
Class of workers:
Master electrician, with per week salary = $750 per worker
Apprentices, with per week salary = $350 per worker
Number of inspection hours required from each master electrician = 3 hours
Total inspection hours for the project = 25 hours
Average number of master electricians needed = 25/3 = 8.333 = 8
Number of each type of worker needed:
Master electricians = 8
Apprentices = 22 (30 - 8)
Cost to be incurred for workers:
Master electricians = $6,000 (8 * $750)
Apprentices = 7,700 (22 * $350)
Total labor cost = $13,700
9 master electricians and at least 21 apprentices are needed for the one week project.
According to the local Building Safety Council, each master electrician must spend three hours for inspection time during the one week project.
We estimate the required number of master electricians by dividing the total inspection time and the recommended inspection time for each master electrician:
[tex]n = \frac{25\,\frac{hours}{project} }{3\,\frac{hours}{person} }[/tex]
[tex]n \approx 9 \,\frac{persons}{project}[/tex]
And the minimum number of hired apprentices is found by subtracting the result found above from least required personnel:
[tex]x \ge 30 - 9[/tex]
[tex]x \ge 21[/tex]
9 master electricians and at least 21 apprentices are needed for the one week project.
