Answer:
$52,500
Step-by-step explanation:
The computation of the net operating income is shown below:
But before that we have to find out the contribution margin per unit which is shown below:
Contribution margin per unit is
= Contribution margin ÷ Number of sold units
= $158,000 ÷ 7,900 units
= $20
Now the operating income is
= Selling units × contribution margin per unit - fixed expenses
= $20 × 7,800 units - $103,500
= $156,000 - $103,500
= $52,500
