Answer:
$131,180; 21.53%
Explanation:
The controllable margin and the return on investment for 2017 are as follows:
Controllable Margin = Sales - Variable cost - Controllable fixed cost
= $567,200 - $340,320 - $95,700
= $131,180
Return on investment = Controllable Margin ÷ Average operating assets
= $131,180 ÷ $609,100
= 0.2153
= 21.53%
