Explanation / Answer

Let the number of Bundles purchased from Ford Motors, Admiral Motors and Chrysalis be x, y and z

5x + 5y + 10 z > 550 ==> x + y +2z > 110....1)

5x + 10y + 5z > 500    ==> x + 2y +z > 100.....2)

10x + 5y + 5z > 550    ==> 2x + y +2z > 110....3)

Adding eqn 1) , 2) and 3)

4x + 4y + 4z > 320

x + y + z > 80 ......4)

1) - 4) ==> z >30

2) - 4) ==> y >20

3) - 4) ==> x >30

Fred motors = 30 package

Admiral motors = 20 package

Chrysalts = 30 package

Cost = 30*500,000 + 20*400,000 + 30*300,000 = 32,000,000
