Question

A town with a population of 7,000 grows 4% per year. Find the population at the end of

9 years.

Answer 1

If something increases by 4%, that is the same thing as being multiplied by 1.04.

7000 x 1.04 = 7280 <--- This is population after one year, because the problem says 4% is the growth rate for ONE year.

You can repeat the process for nine years instead of one.
