Final answer:
The break-even point in units can be calculated using the formula: Break-even point = Fixed costs / (Selling price per unit - Variable costs per unit). Before the purchase of the new machine, the break-even point is 10,000 units. After the purchase of the new machine, the break-even point is 7,000 units. Therefore, the purchase of the new machine would decrease the break-even point in units.
Step-by-step explanation:
The break-even point in units can be calculated using the formula:
Break-even point = Fixed costs / (Selling price per unit - Variable costs per unit)
Before the purchase of the new machine, the fixed costs are $28,000 and the variable costs are $3.60 per unit. Therefore, the break-even point is:
Break-even point = $28,000 / ($5.00 - $3.60) = 10,000 units
After the purchase of the new machine, the fixed costs increase by $8,000 and the variable costs decrease by $0.40 per unit. Therefore, the break-even point with the new machine is:
Break-even point = ($28,000 + $8,000) / ($5.00 - $3.60 + $0.40) = 7,000 units
So, the purchase of the new machine would decrease Mullis Corp.'s break-even point in units from 10,000 to 7,000 units.
