In formulating a transportation problem as linear programming model, which of the following statements are correct?
A) There is one constraint for each supply location.
B) There is one constraint for each demand location.
C) The sum of decision variables out of a supply location is constrained by the supply at that location.

All of the statements are correct. 
A) There is one constraint for each supply location because the total amount sent from that location must be less than or equal to the supply available at that location.
B) There is one constraint for each demand location because the total amount received at that location must be equal to the demand of that location.
C) The sum of decision variables out of a supply location is constrained by the supply at that location because the total amount sent from that location cannot exceed the supply available at that location.
D) The sum of decision variables out of all supply locations to a specific demand location is constrained by the demand at that location because the total amount received at that location must be equal to the demand of that location.
