Answer:
1. $44,160
2. $43,040
Explanation:
The formula to compute the net operating income is
= Total sales - variable cost - fixed expenses
where,
Contribution margin = Total sales - variable cost
1. Increased sales = Increased units × selling price per unit
               = $7,040 units × $33 per unit
               = $232,320
 Variable cost = Increased units × variable cost per unit
             =  $7,040 units × $19 per unit
             = $133,760
 Fixed expenses = $54,400
Now operating income = $232,320 - $133,760 - $54,400
                   = $44,160
2. Decreased sales = Decreased units × selling price per unit
               = $6,960 units × $33 per unit
               = $229,680
 Variable cost = Decreased units × variable cost per unit
             =  $6,960 units × $19 per unit
             = $132,240
 Fixed expenses = $54,400
Now operating income = $229,680 - $132,240 - $54,400
                   = $43,040
