Question 948907: The population of New Haven was 148,220 in 2005. Since then the population has been decreasing at an annual rate of 2.9%. If this rate of decline continues, what will the population be in the year 2015?

Y = a*bx where a is the starting amount; b is the decay rate (decreasing subtract from 1) ; x is time

Answer by macston(5194) (Show Source): You can put this solution on YOUR website!
a=starting amount; b=decay rate (decreasing subtract from 1)(1-r) ; x is time;
r=rate=2.9%=0.029
x=2015-2005=10 years
This equation should be written:

Y=148220(.745)=110433 ANSWER: The population at this rate of decline will be 110,433 in 2015.
