Deon Hahn · Answer 1

Part a

alligators: y=20 (1.25) ^x where x is years

crocodiles: y=10x+25

part b

alligators

y=20 (1.25^4) = 48.82 so about 48 to 49

exponential growth since the number of alligators increases by a percentage

crocodiles

y = 10 (4) + 25 = 65

linear growth since the number of crocodiles increases by the same amount each year
