How can I Determine the operating income using variable-costing approach.

Example:
Sales: 26,000 units at $17 each
Actual production 30,000 units
Expected volume of production 33,000 units
Manufacturing costs incurred
Variable $220,000
Fixed 93,000
Non manufacturing costs incurred
Variable $ 88,000
Fixed 42,000
Anything will help Thanks

minusVariable manufacturing costs for sold Qty 190,666.67

minusVariable non manufacturing costs for sold Qty 76,266.67

Thanks for your note, and sorry for the misunderstand.
But the solution I wrote is for discussion, I'm not sure if it's 100 % right.
