The population of askewville in 2016 was 229 and is declining at 3% per year. if this trend continues, when will the population of askewville reach 100 residents?

Around 27.2 years later

Step-by-step explanation:

This is compound decline problem. We use the formula:

Where

F is future amount (100)

P is present amount (229)

r is the rate of decrease (3% means 3/100 = 0.03)

t is the time in years (which we want to find)

So, lets substitute and solve:

So, around 27.2 years later, the population would reach 100

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
