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.
