Consider the following linear program, which maximizes profit for two products: regular $($R$)$ and super $($S$)$:

MAX $5$R $+75$S

s$.$t$.$

$1\mathrm{.}2$ R $+1\mathrm{.}6$ S $<=600$ assembly $($hours$)$

$0\mathrm{.}8$ R $+0\mathrm{.}5$ S $<=300$ paint $($hours$)$

$0\mathrm{.}16$ R $+0\mathrm{.}4$ S $<=100$ inspection $($hours$)$

R$,$ S $>=0$

See the sensitivity report provided below:

The upper limit of the super product $($s$)$

$10\mathrm{.}8$

$120$

$12\mathrm{.}5$

It is "infinity", so there is no upper limit$.$

None of the above
