Answer:

See Explanation

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:

$\%Change = (New - Old)/(Old) * 100\%$

$\%Change = (55-45)/(45) * 100\%$

$\%Change = (10)/(45) * 100\%$

$\%Change = (1000)/(45) \%$

$\%Change = 22.22\%$

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:

$\%Change = (New - Old)/(Old) * 100\%$

$\%Change = (35-45)/(45) * 100\%$

$\%Change = (-10)/(45) * 100\%$

$\%Change = -(1000)/(45) \%$

$\%Change = -22.22\%$

The negative sign indicates percentage decrease

So, this means there is a 22.22% decrease
