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∙b^x where a is the starting amount, b is the decay rate (decreasing subtract from 1) and x is time.
We will use this equation: 148,220×0.971^x=y The time is between 10 years, so we'll put 10 in as x. 0.971^10=0.745061803×148,220=110433.06 So, the population will be about 110,433 people.
