Hi there!

nearest percentage=64%

1.Subtract starting value and final value:

$1599-579=1020$

2.Divide it by the starting value:

$1020*1599= 0.6378986866791744840525328330206378986$

3.Multiply the term by 100:

$0.6378986866791744840525328330206378986$ · $100= 63.78986866791744840525328330206378986$

4.Round the term:

$63.78986866791744840525328330206378986=64$

Therefore, the decrease of the total 8 years was 64%.
