b (1). Â there was an Increase in Inventory
b (2). fixed manufacturing overhead cost released from inventory during Year 4 is  $28,000 Â
Explanation:
Year 4
Variable costing net operating income    = $984,400
Absorption costing net operating income  =  $1,012,400
Since,
Variable costing net operating income < Absorption costing net operating income
Therefore, there was an Increase in Inventory
Fixed manufacturing overhead cost released from inventory during Year 4
Absorption costing net operating income      =  $1,012,400
Less Variable costing net operating income    = ($984,400)
Fixed Costs                               =   $28,000 Â
