67%

The population of people in a town is modelled using the formula $P = a(10^{bt})$ where $t\,$ is the time in years since 2001, and $a\,$ and $b\,$ are constants.

Explain what the value of $a\,$ represents

[1]

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 $a\,$ and the value of $b$ .
