To travel the Erie Canal , a boat must go through locks that raise or lower the boat. Traveling east , a boat would have to be lowered 12 feet at Amsterdam , 11 feet at Tribes Hill , and 8 feet at Randall. By how much does the elevation of the boat change between Amsterdam and Randall?

at each stop the boat is lowered 8+12+11=31 feet

The correct answer is:

31 feet.

Explanation:

The boat is lowered 12 feet at Amsterdam. It is then lowered 11 feet at Tribes Hill; this is a running total so far of 12+11 = 23 feet.

The boat is then again lowered 8 feet at Randall. This makes a total of 23+8 = 31 feet that the boat is lowered.
