The population of plano is approximately 280,000 in 2006. plano is growing at a rate of 7% per year. what was the population in 1990?

So you would divide 280,000 from 2006 (277,994) which will tell you the amount of increase per year. So when you subtract 2006 from 1990 after you have that number btw it's 16 so you're gonna to take the growth amount (277,994) and times it by 16 (4447904) so for the review, you always have to break it into little pieces then build it back up. I hope this helped.
