The linear equation in slope intercept form for population of Jose's town is y = 320x + 2400.
<u>Solution:</u>
Given, the population of Jose's town in 1995 was 2400 and the population in 2000 was 4000,
Let x represent the number of years since 1995.
We have to write a linear equation, in slope- intercept form, that represents this data.
Now, let the change in population per year be p.
Then, population in a year = population change per year number of years + population in 1995.
⇒population in a year = p x + population in 1995
⇒ population in a year = p x + 2400
Here we have an case that, population in 2000 is 4000
Then, number of years since 1995 = 5
So, 4000 = p 5 + 2400 ⇒ 5p = 4000 – 2400 ⇒ 5p = 1600 ⇒ p = 320
Then, our equation will be population in a year = 320x + 2400
Considering the population in a year as y ⇒ y = 320x + 2400.
Hence, the linear equation in slope intercept form is y = 320x + 2400.
<h2>Hello!</h2>
The answer is $101688
<h2>Why?</h2>Since there is not enough information about the rate, let's assume that it's a daily rate.
<h2>Calculations</h2>Let's say:
P : Proceeds
o : original amount
d : number of days
r : percentual rate
So,
Let's make the percentual rate (6,5%) a real number by dividing into 100,
By substituting, we have
$101688
Have a nice day!
