Answer:
$92,820
Step-by-step explanation:
Calculation to determine what The total gross margin for the month under the absorption costing approach is:
First step is to calculate the Absorption costing unit product cost
Direct materials $ 37
 Direct labor $ 27 
Variable manufacturing overhead $ 7
 Fixed manufacturing overhead cost $22 ($59,400/2,700) 
Absorption costing unit product cost $93
Now let calculate the The total gross margin for 
Sales $298,350
 ($ 135 per unit × 2,210 units)
Less Cost of goods sold $205,530
 ($93 per unit × 2,210 units) 
Gross margin $92,820
($298,350-$205,530)
Therefore The total gross margin for the month under the absorption costing approach is:$92,820
