Answer:
$15,000
Step-by-step explanation:
Operating income is the difference between the net sales or revenue generated by a business and the operating expenses of the business.
The operating expenses of the business may be classified into 2 groups namely the fixed and variable costs.
The total operating cost of the business
= ( $9 + $6 + $28 + $32) per barrel
= $75
operating income of both divisions
= 200 ( $150 - $75)
= 200 * $75
= $15,000
