In a transportation problem with 4 sources and 3 destinations, there are typically 4 sources x 3 destinations = 12 decision variables (representing the amount transported from each source to each destination). Additionally, there are 4 supply constraints (one for each source) and 3 demand constraints (one for each destination), totaling 7 constraints.
