Question

Brad created a chart that shows the population of a town will increase to 109,627 people from a current population of 15,200 people. The rate of increase is an annual increase of 6.52%. Brad forgot to include the number of years this increase will take. How many years was it? (Solve algebraically.)

Answer 1

well it says the rate of the annual increase is 6.52%, so every year the population goes up by 6.52%. so if you go through and keep adding 6.52%, how many times do you have to add before you reach 109,627? that is the number of years
