Question

suppose the population of a town is 567 in 2001. The population decreases by 1.5% each year. what will be the population in 2010?

Answer 1

to decrease s number by \(1.5\%\) multiply it by \(100\%-1.5\%=98.5\%=.985\)

Answer 2

to do it 9 times in a row, multiply it by \(.985^9\)

Answer 3

with a calculator, compute
\[\large 567\times (.985)^9\]

Answer 4

494.89?

Answer 5

5x-2=200
5x=202
x=40.4

567(1-.015x) where x is the number of years later
567(1-.015(9))
490 people
Hope this helps! :)
