Answer:
Step-by-step explanation:
First of all, we should understand the problem.
A new method of loading baggage is supposed to reduce labor time by 30%, with other costs unchanged. This means that the cost to load bags will be reduced by 30%, other costs will remain the same 1 dollar per bag.
Differential cost is a cost which changes in response to a given cause of action. In this case, labor labor time is being reduced, Therefore, it is considered as differential cost.
If 30% is deducted from labor time, the labor cost to load bags will be reduced to $2*(1-0.3) = $2 - $0.6 = $1.4
Cost savings per bag would be:
$2 - $1.4 = $0.6 (a)
(b):
Management would use the knowledge of cost savings to decide whether or not to implement the new method.
