Answer:

(a)   Dahl Motors = 8 Cars

       Farthington Auto Sales = 7 Cars

(b)   Roger will purchase from Farthington Auto Sales with higher weekly profit

Step-by-step explanation:

Dahl Motors / Week      

(1)          Car Sold             5         6        7       8         9        10         11          12

(2)          Probability         5%      9%     14%   24%    18%     14%     11%        5%

(3)             (2 x 3 )               0.25   0.54   0.98  1.92     1.62    1.40     1.21     0.60

(4)       Average sales = 0.25  + 0.54  + 0.98  + 1.92 + 1.62 +  1.40  +  1.21+0.60

                                   =   8.52‬ cars/ week

                                   =  8 cars /week

Profit/ Car =    $544

Total weekly profit =  544 x 8

                               =  $4,352

Farthington Auto Sales/ Week    

(1)           Car Sold             5         6        7       8         9        10      

(2)          Probability         8%      21%    31%   24%    10%     6%    

(3)          (2 x 3 )               0.40   1.26   2.17     1.92     0.9     0.6    

(4)       Average sales = 0.40  + 1.26  + 2.17  + 1.92 + 0.90 + 0.60  

                                   =   7.25‬ cars/ week

                                  = 7 cars/week

Profit/ Car =    $651

Total weekly profit =  651 x 7

                               =  $4,557‬

From the calculations above , Roger will purchase from Farthington Auto Sales
