Answer:
a) X ( number of package bought from Fred motors ) = 30
  Y ( number of package bought from Admiral ) = 20
  Z ( number of package bought from Chrysalis ) = 30
b) The smallest total cost = $32,000,000
Explanation:
Given data :
cars types     x           y        z         quantity needed
small          5           5       10            550
medium       5           10       5            500
large          10          5       5            550
cost        $500,000   $400,000  $300,000    Â
Note : x = number of package bought from Fred motors , y = Admiral motors , Â z = Chrysalis motors
The number of packages to be bought from each car manufacturer to keep total cost as small as possible
X ( number of package bought from Fred motors ) = 30
Y ( number of package bought from Admiral ) = 20
Z ( number of package bought from Chrysalis ) = 30
The smallest total cost = ( 30 * 500,000 ) + ( 20*400,000) + (30*300,000 )
                   = $32,000,000
Attached below is the detailed solution
