I’m very confused please explain how to answer #1 with the info provided

Answer 1

Answer:

The population in 2039 would be;

$117,726$

Note: this value can be confirmed by using the spreadsheet to extrapolate values.

Explanation:

Given that the population in 2019 was;

$103,126$

And the population in 2020 was;

$103,856$

The population growth can be modeled with a linear equation;

$y=mx+b$

The slope m is given as;

$m=730$

And b would be the value of y at x=0.

where x is the number of years after 2019;

$b=103,126$

the model can then be written as;

$y=730x+103,126$

At year 2039, x would be;

$x=2039-2019=20$

substituting the value of x into the model;

$\begin{gathered} y=730(20)+103,126 \\ y=117,726 \end{gathered}$

Therefore, the population in 2039 would be;

$117,726$

Note: this value can be confirmed by using the spreadsheet to extrapolate values.
