Waypoint $2\mathrm{.}2\mathrm{.}1.$ The tableau shown in Table $2\mathrm{.}9$ results when the sim$-$

plex algorithm is used to solve a standard maximization LP$.$ Assume

that $a0$ and that $BV=\{x_1,s_1\}.$

For which values of a does the LP have multiple optimal solu$-$

tions?

For which values of $a$ is the LP unbounded?

For which values of $a$ is the LP degenerate?
