@#!*$ econ problem help

[spock86]

I need to make an excel spread sheet. My forumlas arent coming up with the right numbers and my brain is shot.

Anyway I am given some info on my paper I need economic growth- the percent increase in GDP from one year to the next( constant population). It seems simple enough but it's 2:30am and Im half asleep. I need a formula and the first person to give me a working formula will be shipped $5 via pokerstars or full tilt.
