A) Determine the 10-year decay factor for this town’s population.
B) Determine the 1-year decay factor (exactly and approximately to 4-decimal places).
C) Determine the annual percentage change in the town’s population to the hundredth of a percent.
D) Assuming this exponential decay continues, in how many years will the population be reduced to 25% of the original population? Round to the nearest month.
