A biology class at high school predicted that a local population of animals will double in size every 12 years. The population at the beginning of the year 2021 was estimated to be 50 animals. If P represents the population after n years, then which one of the following equations represents the model of the class for the population?

  • P = 12 + 50n
  • P = 50 + 12n
  • P = 50 (2)^12n
  • P = 50 (2)^n/12
