Answer:

See the entire solution process below:

Explanation:

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

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

Where:

#p# is the percent change - what we are solving for in this problem.

#N# is the New Value - 300 million in this problem.

#O# is the Old Value - 76 million in this problem.

Substituting and solving for #p# gives:

#p = (300 - 76)/76 *100#

#p = 224/76 *100#

#p = 22400/76#

#p = 294.7# rounded to the nearest tenth.

Between 1900 and 2006 there was a 294.7% increase in the population of the United States.
