Gabe is at the annual town carnival where Ferris wheel rides cost 5 tickets each and all other rides cost 3 tickets each. He has time for no more than 10 rides, and he can buy no more than 40 tickets. He is also not interested in riding the Ferris wheel more than 4 times. The system below represents the above conditions, where $ x $ is the number of Ferris wheel rides and $ y $ is the number of other rides. \[ \left\{\begin{array}{l|} x+y \leq 10 \\ \hline 5 x+3 y \leq 35 \\ x \leq 4 \\ \hline \end{array}\right. \] Which of these options for the number of rides that Gabe can ride at the carnival are reasonable? Select THREE correct answers. A. $ \square $ 4 Ferris wheel rides and 6 other rides B. $ \square $ 3 Ferris wheel rides and 6 other rides C. $ \square $ 2 Ferris wheel rides and 8 other rides D. $ \square $ $ \square $ 2 Ferris wheel rides and 7 other rides E . $ \square $ 1 Ferris wheel ride and 10 other rides

5. (The minimum number of stages and product distribution)$^2$ A feed containing 30 mole% benzene (A), 25 mole% toluene (B) and 45 mole% ethylbenzene (C) is to be separated by distillation so that 98.5% of benzene and not more than 2% of the toluene should go to the distillate. Calculate the minimum number of ideal stages required. Also estimate the approximate distribution of ethylbenzene, the heavy non-key (HNK) between the distillate and the bottoms using the Fenske equation. The average relative volatilities are $\alpha_{AB} = 2.43$, and $\alpha_{AC} = 5.0$.
