The unit sales to attain the company's monthly target of $28,000 is closest to 4325 units.
We follow these steps to derive the answer:
Let the number of units to be sold be 'x'.
Since
Profit = Total Revenues - (Variable Cost +Fixed Cost), we get
$28,000 = $205x - ($96x+$443440)
$28,000 = $109x - 443,440
$471440 = $109x
x = 4325.137615 ($471440/$109).
