Population of Deer

In 2011, the population of deer in a forest was 650.

In 2012, the population increases by 15%. Write an expression, using only multiplication, that represents the deer population in 2012.

• $650(1.15)$

• $650\left(0.15\right)$

• $650\left(1.15\right)^{2012}$

• $650\left(0.15\right)^{2012}$

In 2011, the population of deer in a forest was 650.

If the deer population continues to increase by 15% each year, write an expression that represents the deer population t years after 2011.

•  $650(1.15)^t$ 

•  $650\left(0.15\right)^t$ 

•  $650+0.15t$ 

•  $650\left(1.15\right)^{ }$
