Multiple Choice

The total cost of the optimal solution to a transportation problem:

A) is calculated by multiplying the total supply (including any dummy values) by the average cost of the cells.
B) cannot be calculated from the information normally included in a transportation problem.
C) can be calculated based only on the entries in the filled cells of the solution.
