The transport cost of the firm can be shown in the given chart:

Formula to calculate the minimized costs

Minimize (Z)=$\underset{i=0,j=0}{\overset{i=3,j=4}{鈭�x_y{C}_y}}$

Where C_y is the transportation cost from location I to j

X_y is the no. of vehicles moving from location I to j

Supply constraints:

X₁₁+X₁₂+X₁₃+X₁₄= 50

X₂₁+X₂₂+X₂₃+X₂₄ = 40

X₃₁+X₃₂+X₃₃+X₃₄ = 75

Demand constraints:

X₁₁+X₂₁+X₃₁ = 50

X₁₂+X₂₂+X₃₂ = 60

X₁₃+X₂₃+X₃₃ = 25

X₁₄+X₂₄+X₃₄ = 30

On Excel, the result will look like this,

Therefore, from the above calculation, we can conclude that the minimum moving costis $720.

From the above calculation, it is clear that about 25 cars moved from location A to D at a cost of $9. To ensure that location A always sends a car to location D, in order to minimize the total moving cost.
