The population of a city can be modeled using the formula P=100,000e⁰.⁰⁵ᵗ, where t is the number of years after 2012 and P is the city's population. Which of the following equations can be used to find the number of years after 2012 that the population will triple to 300,000? a. t = 3 / 0.05e b. t = ln3 / 0.05 c. t = ln200,000 / 0.05 d. t = log3 / 0.05
