# If I buy a stock for $100.00 and it appreciates to$200.00, what is the best formula to calculate the % increase?

See the entire solution process below:

#### Explanation:

For calculating the percent change between two points in time I use the follow formula:

$p = \frac{N - O}{O} \cdot 100$

Where:

$p$ is the percent change

$N$ is the New Value - $200.00 for this problem $O$is the Old Value -$100.00 for this problem

Substituting and calculating $p$ gives:

p = ($200 -$100)/($100) *100 p = ($100)/($100) *100 $p = 1 \cdot 100$$p = 100\$

There was a color(red)(100%) increase in the value of the stock.
