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

MAX $50$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$)$

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