Final answer:
The break-even point for Neptune Company without hiring the outside supplier is 12,500 units, calculated using the formula for break-even point in units.
Step-by-step explanation:
Calculating Break-Even Point for Neptune Company
To calculate the break-even point in unit sales for Neptune Company without hiring the outside supplier, we use the formula:
Break-Even Point (units) = Fixed Expenses ÷ (Price per Unit - Variable Expense per Unit)
Fixed Expenses = $25,000 per month
Price per Unit = $4.00
Variable Expense per Unit = $2.00
Break-Even Point = $25,000 ÷ ($4.00 - $2.00)
Break-Even Point = $25,000 ÷ $2.00
Break-Even Point = 12,500 units
Therefore, Neptune Company needs to sell 12,500 units of the toy each month to break even if they do not hire the outside supplier.
