Answer 1

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
