Answer:

See the entire solution process below:

Explanation:

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.
