Answer:
The change in net operating income after the changes by $14,200
Explanation:
For computing the change in net operating income, first, we have to compute the contribution per unit which is shown below:
Contribution per unit = Selling per unit - variable cost per unit
= $190 per unit - $76 per unit
= $114 per unit
where,
The selling per unit = (Sales revenue ÷ number of units)
= ($190,000 ÷ 1,000 units)
= $190 per unit
The variable cost per unit = (variable cost ÷ number of units)
= ($76,000 ÷ 1,000 units)
= $76 per unit
Now the change in operating income equals to
= (increased sales units × contribution per unit) - advertising cost
= (300 units × $114 per unit) - $20,000
= $34,200 -$20,000
= $14,200 increase
