During a 5-day festival the number of visitors tripled each day If the festival opened on a Thursday with 345 visitors what was the attendance on that Sunday?

Answer 1

Since the crowd is growing exponentially, this is solved using the following formula. f(x) = C*b^x C = the constant 345. B is the amount the crowd is growing exponentially, in this case it is tripling so it is growing by a factor of 3. Thursday is the start day or day 1, so b is raised to a factor of 0 because any number raised to the 0 power = 1. So Thursday = b^0. Sunday = b^3 because it is 3 days later. Final equation: f(3) = 345(3)^3 = 9315 If you were looking for the number of the crowd on Saturday the equation would look like f(2)=345(3)^2 - 3105, and so forth.
