3 x 50 x 18 x 2

3 x 50 = 150

18 x 2 = 36

150 x 36 = 5400

A forest has 800800800 pine trees, but a disease is introduced that kills \dfrac{1}{4} 4 1 start fraction, 1, divided by, 4, e

This is a perfect example of exponential decay. In this case the growth factor should be represented by a fraction, and it is! This forest, starting out with apparently ( 800? ) pine trees, has a disease spreading, which kills 1 / 4th of each of the pine trees yearly. Therefore, the pine trees remaining should be 3 / 4.

Respectively 3 / 4 should be the growth factor, starting with 800 pine trees - the start value. This can be represented as such,

$P( t ) = a( b )^t$ - where a = start value, b = growth factor, t = time ( <em>variable quantity</em> )

____

Thus, the function $P( t ) = 800( \frac{3}{4} )^t$ can model this problem. The forest after t years should have P( t ) number of pine trees remaining.
