Answer:
4,166.66 units per year
Explanation:
Break-even is defined as the production volume at which the cost incurred in the production process is equal to the revenue earned.
Production above this point will result in positive revenue for the company.
The formula for break-even is
Break-even= Fixed cost ÷ (Difference in cost of labour per unit)
Difference in labour cost is the gain from this process. When it involves sales the denominator is Sales price less variable cost.
Break-even = 15,000 ÷ (1.4 - 0.2)
Break-even = 12,500 units
Production will have to exceed 12,500 units to justify purchase of the robot for 3 years.
Units produced per year will be
12,500 ÷ 3 = 4,166.66 units per year
