Assume you started with the table on the left and after performing the Assignment Method ended up with the table on the right. What is the cost of a possible optimal $($minimum cost$)$ assignment?

$\backslash$table$[[$Job$,$Resource$],[$A$,$B$,$C$,$D$],[1,7,3,4,8],[2,5,4,6,5],[3,6,7,9,6],[4,8,6,7,4]]$

$\backslash$table$[[$Resource$],[$Job$,$A$,$B$,$C$,$D$],[1,4,0,0,0],[2,1,0,1,1],[3,0,1,2,0],[4,4,2,2,0]]$
