Give the step-by-step reasoning process and then the final answer. If one Burmese python can eat one 50-cm alligator per week, how many Burmese pythons would it take to eat fifteen 50-centimeter alligators in three weeks?
15 alligators eaten over a period of 3 weeks is a rate of 15 / 3 = 5 alligators per week. Under the normal rate of 1 alligator per week per python, it would take 5 / 1 = 5 pythons to eat 15 alligators in 3 weeks.
The final answer: 5.
