Answer: The amount of gross margin Mazer would report if the company uses absorption costing is $1350.
Step-by-step explanation:
Given that,
Mazer Manufacturing Company produced = 2,000 units of inventory
Units Sold = 1,800 units
Variable product cost = $4 per unit
Fixed manufacturing overhead cost = $2,500
Sales price of the products = $6 per unit
Fixed manufacturing cost per unit =

=

= $1.25 per unit
Unit Product cost under Absorption costing = Variable product cost + Fixed manufacturing cost per unit
= 4 + 1.25
= $5.25
∴ Gross margin under Absorption costing = Sales Revenue - Cost of goods sold
= Units sold × sales price - Units sold × Unit Product cost under Absorption costing
= 1800 × 6 - 1800 × 5.25
= 10800 - 9450
= $1350
