Suppose the population of a town is 3,400 in 2000. the population decreases at a rate of 2% every 20 years. what will be the projected population in 2040? round your answer to the nearest whole number.
options:
a)4,115
b)3,985
c)3,265
d)5,265

The formula would be
A=p (1-r)^t

P 3400
R 0.02

Since it decreases every 20 years
From 2000 to 2040 it decreases 2 times so
T 2

A=3,400×(1−0.02)^(2)
A=3,265

It's c

The symbol < means ‘less than’ and > means ‘greater than’. But your symbol has an extra line underneath, almost like an equals sign (=). It means ‘less than or equal to’.
I can’t type your symbol, but will use =< instead.
So: 2=We are told x is an integer (whole number) so the possible solutions are the consecutive numbers from 2 to 8.
That is: x = 2, 3, 4, 5, 6, 7 or 8.
