$(x,Y).$ When entering a range $($i$.$e$.$ range of optimality or range of feasibility$)$:

Use square brackets when the endpoint is included $($all values except infinity$)$

Use parenthesis when the endpoint is "not" included.

Use $-$inf and inf to represent values of minus infinity and infinity respectively.

For example, if the lower endpoint is $5$ and the upper endpoint is $7\mathrm{.}25,$ you would enter $[5,7\mathrm{.}25].$ If the lower endpoint is minus infinity and the upper endpoint is $1\mathrm{.}65,$ you would enter $(-$inf, $1\mathrm{.}65].$

If the linear program cannot be solved, specify one of the following for the optimal value and specify $0$ for all other answers:

$1-$ Solution is suboptimal

$2-$ Empty feasible region

$3-$ Unbounded feasible region

$4-$ All other reasons

Enter all values to two decimal places.
