What is the growth factor associated with the following growth rate: 30% decrease

fenix001 [56]

Given:

Growth rate = 30% decrease

To find:

The growth factor associated with the given growth rate.

Solution:

The general exponential function is:

$y=a(1+r)^x$

$y=a(b)^x$

Where, a is the initial value, r is the growth rate in decimal and $b=1+r$ is the growth factor.

It is given that the growth rate is 30% decrease. So,

$r=-30\%$

$r=-\dfrac{30}{100}$

$r=-0.3$

Now,

$b=1+r$

$b=1+(-0.3)$

$b=1-0.3$

$b=0.7$

Therefore, the growth factor is 0.7.

I need to know the step by step on how to solve this question

My father taught me a method that I call, 'throwing some thing over the wall'. There is a sample equation for the first picture that shows you how it works. It's a great way to help isolate the variable and I hope that it works for you. The second picture contains the answers I got through the use of this method. I'm sorry for the messy handwriting; I was on a bus.
