Answer:
    A                              B              C               D
Production Costs :    2004   -   2005   -   2006
Gauss Grip :             $2,300 -  $2,700  -  $2,900
Air Gauss :                $1,900 -   $2,200 -  $1,700
Gauss Gel :               $2,000 -  $2,500 -  $1,800
Profit :                          2004   -   2005   -   2006
Gauss Grip :             $12,000 - $16,000 - $18,000
Air Gauss :               $10,000 - $14,000 -  $16,000
Gauss Gel :              $11,000  - $16,000 - $14,000
As we know:
Revenue = Cost + Profit
