Answer:
If the Profit under absorption costing is higher, this means ending inventory is higher than beginning inventory.
Amount of Per units fixed cost will be: $55,080 / 10,800 = 5.1 per unit
Profit impacting units = ($110,840 - $83,000) / 5.1
Profit impacting units = $27,840 / 5.1
Profit impacting units = 5458.823529
Profit impacting units = 5,459 units
So, between the beginning and the end of the year, the inventory level increased by 5,459 units
