Your answer is partially correct. Mute swans were imported from Europe in the nineteenth century to grace ponds. Now there is concern that their population is
growing too rapidly, edging out native species. During the 2000s, many states created mute swan controls. The goal was to reduce
the mute swan count from 14,313 in 2002 to 3000 swans by 2013.

b. Using an exponential model, what would be the decay factor needed?
