Hi this may seem like a basic question but i had a real hard time solving it. based on the chart i thought the answer should be:
calc top 5 rev:
in 2009 :74b*.48=35.52b
in 2003: 38b*.32=12.16b
so the increase should be: (35.32-12.16)/12.16=190%
so i thought C is the right answer, but the answer key shows that the right answer should b D. Can anyone help me understand how D is the right answer? thanks so much!
