Answer:
$45,000
Explanation:
In this problem, assume that the wage for operators and sales people are based on production volume and therefore computed as variable costs alongside raw materials.
If the company is breaking-even, the following relationship is true:
[tex]Revenue = Fixed\ Costs+Variable\ Costs[/tex]
At a volume of 4,000 units selling at $20 each, the fixed costs must be:
[tex]4,000*\$20=FC+(\$10,000+\$15,000+\$10,000)\\FC = \$80,000-\$35,000\\FC=\$45,000[/tex]
Fixed Costs are $45,000.
