In class we are learning about relative rate of growth and here's this question I don't understand how to approach:

The table below shows the cumulative number of AIDS deaths worldwide. Find the absolute increase in AIDS death between 2003 and 2004 and between 2006 and 2007. Find the relative increase between 2006 and 2007

Year 2003 2004 2005 2006 2007 Cases 30.2 33.3 35.5 37.6 39.6

Apparently, the absolute increase is in millions and relative increase is in percent.
