Answer:
               80,000 units 100,000 units   120,000  units
Variable cost     $1,520,000  $1,900,000    $2,280,000
Total costs      $1,820,000   $2,200,000   $2,580,000
Explanation:
Activity Level  Â
Finished Units         80,000 units 100,000 units   120,000  units
Variable Costs: Â Â
Direct Materials(Units × $5) $400,000   $500,000   $600,000
Direct Labor(Units × $6)    $480,000   $600,000   $720,000
Overhead (Units × $8)     $640,000   $800,000   $960,000
Total Variable Costs     $1,520,000  $1,900,000   $2,280,000
Fixed Costs Â
Depreciation            $200,000       $200,000   $200,000
Supervision            $100,000       $100,000   $100,000
Total Fixed Costs        $300,000       $300,000   $300,000
So, Total costs        $1,820,000   $2,200,000   $2,580,000
