Concepts

Percent Change

Percent change refers to how much, as a percentage, a quantity increases or decreases. The formula for percent change is $\frac{FV-IV}{IV} * 100 = PC$. Keep in mind percent change is not negative, but can be written as 40% decrease or 40% increase.

• FV = Final Value
• IV = Initial Value
• PC = Percent Change (%)

Application

How Does this Apply Here?

We are being asked to find the percent change, or the change in the price of the sweater from $20 to $12. Thus, we will have to use the aforementioned formula. $20 is the initial value and $12 is the final value.

Solving

Solving for Percent Change

Step 1: Plug in values.

• $\frac{12-20}{20} * 100$

Step 2: Simplify.

• $\frac{8}{20} * 100$
• $800/20$
• $40$

Therefore, the answer is D. 40%.
