The price of the product decreased by 10%and then decreased by 20% . calculate total percentage change between the final and ini
aev [14]

What is percentage change?

By quantifying the difference between two numbers and expressing it as an increase or decrease, the Percentage Change Calculator (percent change calculator) may determine the percentage change.

The initial price V_{1} (100%) was decreased by 10%., then this reduced price is reduced more by 20% that becomes the final price V_{2} which is 72.

Calculate percentage change from $V_{1}=100$ to $V_{2}=72$.

=& \frac{\left(V_{2}-V_{1}\right)}{\left|V_{1}\right|} \times 100 \\

=& \frac{(72-100)}{|100|} \times 100 \\

=& \frac{-28}{100} \times 100 \\

=&-0.28 \times 100 \\

=&-28 \% \text { change } \\

=& 28 \% \text { decrease }
