Answer: The equation would be P(t) = 100t + 2003
Step-by-step explanation: The equation for the population of snakes over time would be P(t) = 100t + 2003, where P represents the population of snakes and t represents the time in years. The initial population of snakes is 2003, and the population increases by 100 snakes per year.
Therefore, after t years, the population of snakes would be 100t more than the initial population of 2003.
