Answer:
Results are below.
Explanation:
<u>The variable costing method incorporates all variable production costs (direct material, direct labor, and variable overhead).</u>
Unit product cost= direct material + direct labor + variable overhead
Unit product cost= $71
<u>Now, the total sales and total variable cost:</u>
Total sales= 4,300*137= $589,100
Total variable cost= 4,300*71= $305,300
<u>Finally, the variable costing margin:</u>
Variable costing margin= total sales - total variable cost
Variable costing margin= 589,100 - 305,300
Variable costing margin= $283,800
