  1. Working backwards from \(\boldsymbol { I }\), use dynamic programming to find the maximum number of bags that can be collected when driving from \(A\) to \(I\). You must complete the table opposite as your solution.
  2. State the route that the collector should take in order to collect the maximum number of bags.
