Answer:
141,667 units
Explanation:
The sales less the variable cost gives the contribution margin. The contribution margin less the fixed cost gives the net operating income.
As such, the net operating income/loss is the difference between the sales and the total costs .
Let the amount of sales in units be y then,
250y - 130y - 1,500,000 = 200,000
120y = 1,700,000
y = 1700000/12
= 141,667 units
