Example: Computing Percent Change
First, determine the percentage change from a forecast amount of $658
to an actual amount of $700. Second, determine what the new amount
would be if it were 7% below the original forecast.
Answer: $700 represents a 6.38% increase over the original forecast of
$658. A decrease of 7% would result in a new actual amount of $611.94.
Example: Computing Compound Interest
You purchased stock in 1995 for $500. Five years later, you sell the stock
for $750. What was the annual growth rate?
