Percent of Change

Key Questions

What is the percent change formula?

The percentage change formula is:

$(\frac{X_{2}}{X_{1}} - 1) \cdot 100$ $(X_2 / X_1 - 1) * 100$

where $X_{1}$ $X_1$ is the original value and $X_{2}$ $X_2$ is the final value.

Example:

If Google's stock price increases from $500 to $575, it has increased by 15%.

$(\frac{575}{500} - 1) \cdot 100 = 15 %$ $(575 / 500 - 1) * 100 = 15%$

How do you solve a percent change equation?

Answer:

See the process below:

Explanation:

The formula for calculating the percent change in a value between two points in time is:

$p % = \frac{N - O}{O} \cdot 100$ $p% = (N - O)/O * 100$

Where:

$p$ $p$ is the percent change

$N$ $N$ is the New Value.

$O$ $O$ is the Old Value

Take the old and new values you are given in the problem, substitute them for $O$ $O$ and $N$ $N$ and calculate the percent change

What is percent change?

If $x$ $x$ is some changing quantity, and $Delta x$ be the change in $x$ -value, then the percentage change can be found by

${Delta x}/x times 100$

Example

What is the percentage change (discount) of $12 discount on $300 item?

${12}/{300} times 100=4%$ discount

I hope that this was helpful.
