The fair market rental rate for Columbus was $730 in 2013 and $551 in 2003. Find the rate of change for rent in Columbus during this period.

Respuesta :

Let rental rate be denoted by 'y' and years be denoted by 'x'

coordinates become: (2003,551) (2013,730)

Rental rate in  = $551(y1)

Rental rate in =$730(y2).

So, change in rate = [tex]730-551=179[/tex]

Years given are 2003(x1) and 2013(x2) so, change is [tex]2013-2003=10[/tex]

Here, to find the rate we use the slope formula:

[tex]\frac{y2-y1}{x2-x1}[/tex]

Now putting the values of coordinates in the formula we get:

[tex]\frac{730-551}{2013-2003}[/tex]

= [tex]\frac{179}{10}[/tex]

= 17.9

So, the rate of change for rent is $17.9
