Consider the transportation table below. The solution displayed was obtained by performing some iterations of the transportation method on this problem.

$\backslash$table$[[$Source$,$Destination,Capacity$],[1,,2,,3,],[$A$,40,$$$30,,$$$30,10,$$$5,50],[$B$,,$$$10,30,$$$10,,$$$10,30],[$C$,,$$$20,30,$$$10,45,$$$25,75],[$Demand$,40,,60,,55,,]]$

The total cost of the current solution provided $=$ dollars.
