In the year 2000, the population of

Adams County was 60,000 residents.

Each year since, its population has

decreased 0.1%. Predict what the

population of Adams County will be

in the year 2015.

12,353 51,604 or 59,106

Answer: 59106

Step-by-step explanation:

We would apply the formula for exponential decay which is expressed as

A = P (1 - r) ^ t

Where

A represents the population after t years.

t represents the number of years.

P represents the initial population.

r represents rate of growth.

From the information given,

P = 60000

r = 0.1% = 0.1/100 = 0.001

t = 2015 - 2000 = 15 years

Therefore

A = 60000 (1 - 0.001) ^15

A = 60000 (0.999) ^15

A = 59106
