PLEASE ADD AN EXPLANATION AND HELP MEEEEEEEE

Answer 1

The population increases by 12% each year.

Answer 2

Answer:

It is 12%

Step-by-step explanation:

A or 87000 in this case represents the starting value, which is this case is the starting population of the town. r or 1.12 represents the percentage increase, if it increases by 12% than the next year has 1.12 times as many people as the previous year so this is represented by 1.12 rather than say 0.12 which would indicate a 88% decrease instead.  t is the time, no. of years in this case, that has elapsed since 1996. This formula basically means that a town population of 87000 increases by 12% for every year of time that elapses.
