$y = \frac{1}{4} {(1.2)}^{t}$

Step 1

Since $1.2$ is greater than $1$ , there is an exponential growth.

$a {(1 + r)}^{t}$

Step 2

Setup the rate equation.

$1 + r = 1.2$

Step 3

Solve $1 + r = 1.2$ for $r$ to determine the growth factor.

Step 3.1.1

Subtract $1$ from both sides of the equation.

$r = 1.2 - 1$

Step 3.1.2

Subtract $1$ from $1.2$ .

$r = 0.2$
