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
Step-by-step 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
Note : x = number of package bought from Fred motors , y = Admiral motors , 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
