Answer:
$60,000 increase.
Step-by-step explanation:
Calculation to determine by how much would the company's gross margin increase or decrease under absorption costing
First step is to calculate FOH per unit at 30,000 unit level
FOH per unit=$150,000/30,000 units
FOH per unit = $5 FOH per unit
Second step is to calculate FOH per unit at 50,000 unit level
FOH per unit=$150,000/50,000 units
FOH per unit= $3 FOH per unit
Now let determine by how much would the company's gross margin increase or decrease under
Gross margin=($5 - $3)*30,000
Gross margin = $2 x 30,000
Gross margin = $60,000 increase
Therefore by how much would the company's gross margin INCREASE under absorption costing is $60,000
