somebody help me plz
ill try to help
ok thanks :)
is there any multiple choice answers?
sadly no :(
ok, multiply 4% per year by the 14 years
so times 535,000 by 1.04, then that number by 1.04, and continue on until I've done it 14 times?
I believe so, just were did you get the 1.04? did you mean 0.04 for 4%?
Sounds very similar to an "interest" problem. Where the amount A equals the Principal (initial quantity) times the quatitiy 1 + rate to the power equal to the number of years. For population we could write: P = (initial population) times the quantity 1 + rate of growth to the power equal to the number of years. P = 535,000(1 + .04)^14 Can you solve that? You need to use a calculator with a x^y key.
P =535,000 (1.04)^14 P=535,000 X 1.731676448 = 926,447
