The change in elevation between Amsterdam and Randall is 19 feet.

#### Explanation:

Say you go into the first lock(Amsterdam) at 0 ft. The boat is then lowered 12 feet or -12ft below 0. The boat is then lowered another 11ft at Tribes Hill and 8ft at Randall. Since the question is simply asking the difference in elevation between Amsterdam and Randall you simply have to add the loss in elevation at Tribes Hill and Randall (11+8).
