Answer:
$53,100
Explanation:
Both sales and variable cost are dependent on the number of units sold.
The sales less the variable cost gives the contribution margin. The contribution margin less the fixed cost gives the net operating income.
As such, the net operating income/loss is the difference between the sales and the total costs
As such, the company's net operating income
= $260,000 - $140,100 - $66,300 + $570,000 - $319,800 - $125,500 - $125,200
= $53,100
