Question

The following shows annual production costs and profits at Gauss-Jordan Sneakers, Inc. 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 Use matrix algebra to compute the revenues from each sector each year.

Answer 1

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

*Proper Matrix format is also attached in the picture with this answer.

Production Costs :    2004  2005  2006

                                  $\left[\begin{array}{ccc}2300&2700&2900\\1900&2200&1700\\2000&2500&1800\end{array}\right]$

Profit :                         2004  2005  2006

                                $\left[\begin{array}{ccc}12000&16000&18000\\10000&14000&16000\\11000&16000&14000\end{array}\right]$

Revenue :         2004               2005               2006

                  $\left[\begin{array}{ccc}2300+12000&2700+16000&2900+18000\\1900+10000&2200+14000&1700+16000\\2000+11000&2500+16000&1800+14000\end{array}\right]$

Revenue :                2004   2005   2006

                             $\left[\begin{array}{ccc}14300&18700&20900\\11900&16200&17700\\13000&18500&15800\end{array}\right]$
