(1). (a) Consider the following Balanced Transportation problem and the given BFS. Costs are listed in the first table and basic variables listed in the second table. Let \( u_{1}=0 \). What are the other \( u_{i} \mathrm{~s} \) and \( v_{j} \mathrm{~s} \) equal to? (b) Supposed variable \( x_{14} \) enters the basis. Which variable(s) leave the basis? (c) What is the next BFS (write the values of the basic variables only).
