Step-by-step explanation:

The slack variables make up the difference between the sum of the utilizations and the limit. A separate slack variable is needed for each limit. As with the other variables, its minimum value is zero.

For ( ) ≤ lim constraints, the slack variables are on the left side of the equal sign:

  ( ) +s ≤ lim.

__

For ( ) ≥ lim constraints, the slack variables can be on the right side of the equal sign:

  ( ) = s + lim

The more usual representation in a linear programming matrix is ...

  ( ) - s = lim

__

Here, your constraints are "≤", so each equation will have a unique slack variable added to the left side sum.

answer: answer is b.
