See Explanation

Step-by-step explanation:

The question is incomplete; However, one can deduce from the options that the question refers to percentage change.

I will give two illustrations that shows how to calculate percentage change.

Illustration 1

Consider goods x with the following price change.

$Old = \ 45$

$New = \ 55$

The percentage change is:

$\%Change = \frac{New - Old}{Old} * 100\%$

$\%Change = \frac{55-45}{45} * 100\%$

$\%Change = \frac{10}{45} * 100\%$

$\%Change = \frac{1000}{45} \%$

$\%Change = 22.22\%$

This means there is a 22.22% increase

Illustration 2

Consider goods x with the following price change.

$Old = \ 45$

$New = \ 35$

The percentage change is:

$\%Change = \frac{New - Old}{Old} * 100\%$

$\%Change = \frac{35-45}{45} * 100\%$

$\%Change = \frac{-10}{45} * 100\%$

$\%Change = -\frac{1000}{45} \%$

$\%Change = -22.22\%$

The negative sign indicates percentage decrease

So, this means there is a 22.22% decrease
