Answer:
$600,000
Explanation:
Data provided in the question:
Controllable margin = $66,000
Sales = $480,000
Return on investment = 10%
Now,
Return on investment = Controllable Margin ÷ Average Operating Assets
or
10% = $60,000 ÷ Average Operating Assets
or
Average Operating Assets = 60000 ÷ 10%
or
Average Operating Assets = 60000 ÷ 0.01
or
Average Operating Assets = $600,000
