tutorsd6 : Please, share your Math problem...
student : I need to model exponential decay. This is the situation: a population of 130,000 grows 1% per year for 9 years
student : Are you still there?
tutorsd6 : A = 130,000 ( 1+0.01 ) ^ 9
student : I'm confused on how to get (1+0.01)
tutorsd6 : after 9 years the population P = 130,000 ( 1.094 ) = 142220 ( answer )
tutorsd6 : 1 % = 1/100 = 0.01
student : ok, but why was 1 added to it?
tutorsd6 : this is the formula : P = original x ( 1 + r % ) ^ time
