If it grows by x, from 208.6 billion to 250 billion then:
The growth is represented by
208.6 billion*x
It can also be shown by
250 billion - 208.6 billion = 41.4 billion
The two expressions are equivalent so:
208.6 billion*x = 41.4 billion
x = 0.1985 = 19.85%
Good luck! HOpe this helped you!
=)

forget the billion part. take the difference between the two numbers = 41.4. divide it into the original number 208.6 = 5.038. Round it to 5 and divide it into 100 for a number of about a 20% increase.To test it multiply 208.6 by 20% and add it on and the answer will be 250.32 so you'll be close. Try keeping the decimal points to get closer.

You divide 250 by 208,6
Its around 1,1984. Subtract 1 and multiply the result by 100
It would result in 19,84%

250 minus 208.6 equals 41.4 million. Now, take 41.4 million as a percentage of 208.6 (your initial number) and you get 19.8% growth.
