Question

I just need a formula.




A city’s population is declining continuously at a rate of 6.1% each year. If the population of the city is currently 435,410, what will the population of the city be in 8 years?

Answer 1

Fairly sure it is
Original number x multiplier^years

So in this case you do
\[435410 x 0.939^{8}\]

The multiplier for a decreasing statistic is

1-(%/100)

Answer 2

@TripleC how did you get 0,939?

Answer 3

*.939

Answer 4

That's the multipler so you just use that formula I posted

1-(6.1/100) which = .939 :)

Answer 5

Ah thanks!

Answer 6

No problem, if you have one where the population is increasing, just replace the - with a + :)
