Answer:
(1) 0.4 or 40%
(2) $400
Explanation:
1)
Unit selling price = Total sales ÷ Number of units
= $200,000 ÷ 50,000
= $4
Unit variable expense = Total variable expenses ÷ number of units
= $120,000 ÷ 50,000
= $2.4
Contribution margin per unit = Selling price per unit - Variable cost per unit
= $4 - $2.4
= $1.6
Now, computing the contribution margin ratio as
:
Contribution margin ratio = Unit Contribution margin ÷ Unit selling price
= $1.6 / $4
= 0.4 or 40%
(2) Change in net operating income:
= Increase in total sales ×
Contribution margin ratio
= $1,000 × 0.4
= $400
Therefore, the net operating income increases by $400.
