Tacoma's population in the year 2000 was about 200 thousand, and has been growing by about 8% each year. If this continues, what will Tacoma's population be in 2020?

1.08^5 X 200,000=1.4693280768 X 200,000=293,866, the projected population of Tacoma in 2020.
***I am assuming that it is growing 8% every year from the starting point, not a new 8% of the previous year****
You take 8% of the origanlly point which is 200,000.
You find that by solving for X
X = 8
200,000 100
8 * 200,000 = 100X ( I cross multipled across the equal sign and the * means to multiply)
X = 8 * 200,000 (divid by 100 so that the X is alone)
100
Then the number you get you times by 20 because that is the number of years that will go by, then add 200,000 your starting point.
200,000 + 20X = answer
