Final answer:
Using activity-based costing, to earn an operating income of $25,000, the Cobalt Company must sell 8,750 units, calculated by dividing the sum of total fixed costs and desired operating income by the contribution margin per unit.
Step-by-step explanation:
To calculate the number of units Cobalt Company must sell to earn an operating income of $25,000 using the activity-based costing (ABC) equation, we start by determining the total amount of money that must be covered by unit sales. This amount includes both total fixed costs and the desired operating income:
- Total Fixed Costs: $150,000
- Desired Operating Income: $25,000
- Total to be covered: $150,000 + $25,000 = $175,000
Next, we need to calculate the contribution margin per unit, which is the unit selling price minus the unit variable cost:
- Unit Selling Price: $50
- Unit Variable Cost: $30
- Contribution Margin per Unit: $50 - $30 = $20
To find out how many units must be sold to cover the total amount and earn the desired operating income, we divide the total amount by the contribution margin per unit:
- Units Sold = Total to be covered / Contribution Margin per Unit
- Units Sold = $175,000 / $20
- Units Sold = 8,750 units
Therefore, the Cobalt Company must sell 8,750 units to achieve an operating income of $25,000.
