Answer 2

In 2011 The temperature in Darrtown is

`65^(\circ)F`

The temperature increased by 3% in 2012

The temperature will be

`(1+(3)/(100))*65=(1.03)(65)=66.95^(\circ)F`

The temperature decreased by 4.5% in 2013

The temperature will be

`\begin{gathered} (1-(4.5)/(100))*66.95=0.955*66.95=63.93725 \\ \\ (1-(4.5)/(100))*66.95=64^(\circ)F\text{ (to the nearest whole number)} \end{gathered}`

Therefore, the temperature in 2013 is 64 degrees Fareheint
