 A company is launching a new product. In order to manufacture this new product, two types of labour are required. The new product required 5 hours of skilled labour and 5 hours of semi skilled. 

A skilled employee is available and is currently paid $10 per hour. A replacement would, however, have to be obtained at a rate of $9 per hour for the work that would otherwise be done by the skilled employee. The current rate for semi skilled workers is $5 per hour and an additional employee would be appointed for this work. 

What is the relevant cost of labour to be used in making one unit of the new product? 

A

 $45 

B

 $50 

C

 $70 

D

 $75

 The correct answer is: $70. 

The rate of $10 per hour is not relevant because it would be paid anyway. The relevant hourly rate is the incremental cost of $9 per hour. 

Skilled labour 5 hour × $9            =      45 

Semi skilled 5 hours × $5            =      25 

Total                                                  =    $70 

If you chose $45 you missed out the semi skilled labour. 

If you chose $50 you costed all of the hours at the $10 per hour which is the rate for the skilled employee, but not the relevant one in this scenario. 

If you chose $75 you then added the 5 hours at $5 to this $50. In other words all hours were costed using normal hourly rates.
