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

Answer 1

Kennedy Adams

See the entire solution process below:

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

#p = (N - O)/O *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 * 100#

#p = 100#

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

The formula to calculate the percentage increase in the value of the stock is:

[ \text{Percentage Increase} = \frac{{\text{Final Value} - \text{Initial Value}}}{{\text{Initial Value}}} \times 100% ]

Using the given values: [ \text{Percentage Increase} = \frac{{200.00 - 100.00}}{{100.00}} \times 100% = \frac{{100.00}}{{100.00}} \times 100% = 100% ]

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
