Answer:
Gunst should produce 500 Bio-mutant games: 
- total contribution margin = $71 x 500 = $35,500
Explanation:
                                    Android          Bio-mutant          Cyclops
selling price                  $100                 $107                   $125
labor                               $48                  $24                     $60
direct materials               $9                    $8                       $16
variable overhead          $7                     $4                        $9
contribution margin      $36                   $71                      $40
labor hours                        4                       2                          5
Bio-mutant generates by far the largest contribution margin and requires the least direct labor hours.
Gunst should produce 500 Bio-mutant games: 
- total revenue = $107 x 500 = $53,500
- total contribution margin = $71 x 500 = $35,500
If it produces 250 Android games its total contribution margin will = $9,000
If it produces 200 Cyclops games its total contribution margin will = $8,000
