Explanation:
a) Costs Calculations:
             Unit cost      Total cost
Variable        $5          $75,000 ($5 x 15,000)
Fixed Cost     $25         $375,000 ($375,000/15,000)
Full Cost      $30         $450,000 ($30 x 15,000, or $75,000 + $375,000)
Markup        $15         $225,000 ($900,000 x 25% returns)
Price to charge $45 Â Â Â Â Â Â Â $675,000
