Final answer:
The annual percent change in the population of town A is 725%.
Step-by-step explanation:
To determine the annual percent change in the population of town A, we need to calculate the average annual growth rate. If the population increases by 29 every 4 years, we can divide the growth rate by the time period.
So the average annual growth rate is 29/4 = 7.25.
To express this as a percent, we multiply by 100 to get 725%.
Therefore, the annual percent change in the population of town A is 725%.
