Final answer:
Using the high-low method, the cost per machine hour for Portman Company is $1.50 (Option A).
The correct option is A.
Step-by-step explanation:
To calculate the cost per machine hour using the high-low method, we need to identify the variable cost per machine hour. The high and low points are chosen from the activity levels and their corresponding costs.
Let's use January (low) and March (high) in this case:
1. Calculate the variable cost per machine hour:
Variable Cost per Machine Hour = High Cost - Low Cost / High Activity - Low Activity
Variable Cost per Machine Hour = $4,800 - $3,60 / 2,900 - 2,100
Variable Cost per Machine Hour = $1,200 / 800
Variable Cost per Machine Hour = $1.50
Therefore, the correct answer is:
A) $1.50
The correct option is A.
