Answer:
b. 51,429 units
Step-by-step explanation:
If x = Number of units
Net Income = Sales Revenue - Variable Cost - Fixed Cost
or
Net Income = Contribution Margin - Fixed Cost
where,
Net Income = $80,000
Contribution Margin per unit = $3.50
Fixed Cost = $100,000
Contribution Margin = Net Income + Fixed Cost
$3.50x = $80,000 + $100,000
$3.50x = $180,000
Dividing the above equation by $3.50 we get
x = $180,000 / $3.50
x = 51,429 units
Hence 51,429 number of units must be sold to generate the net income of $80,000.
