Moderate -0.8
17 & 9 & 15 & 8 & 20 & 13 & 28 & 4 & 12 & 5 \end{array}$$ The numbers in the list shown above are the weights, in kilograms, of ten boxes. The boxes are to be transported in containers that will each hold a maximum weight of 40 kilograms.
  1. Calculate a lower bound for the number of containers that will be needed to transport the boxes. You must show your working.
  2. Use the first-fit bin packing algorithm to allocate the boxes to the containers.
  3. Using the list provided, carry out a quick sort to produce a list of the weights in ascending order. You must make your pivots clear.
  4. Use the binary search algorithm to try to locate the weight of 9 in the sorted list. Clearly indicate how you choose your pivots and which part of the list is being rejected at each stage.

10 x + 7 y & \leqslant 140
& x + y \leqslant 15
& 2 x + 3 y \geqslant 36
& x \geqslant 0 , \quad y \geqslant 0 \end{aligned} \end{array}$$ (c) Represent these constraints on Diagram 1 in the answer book. Hence determine, and label, the feasible region, \(R\).
(d) Use the objective line method to find the optimal number of each type of cake that Martin should make, and the amount of sugar used.
(e) Determine how much flour and how many eggs Martin will have left over after making the optimal number of cakes. BLANK PAGE \end{document}
