The population of people in a town is modelled using the formula P=a(10bt)P = a(10^{bt})P=a(10bt) where t t\,t is the time in years since 2001, and a a\,a and b b\,b are constants.
Explain what the value of a a\,a represents
In 2008 the population of the town was 54 000. In 2013 the population of the town was 59 000. Use the data to calculate the value of a a\,a and the value of bbb.
