The median player salary for the Dallas Cowboys was $441,300 in 2000 and $1,326,720 in 2008. Write a linear equation giving the median salary y in terms of the year x. Then use the equation to predict the median salary in 2016.

Answer:

Linear function is [tex]y=\frac{221355}{2}x+441300[/tex]

Median salary in 2016 is $2212140

Step-by-step explanation:

Let t = 0 is corresponds to the year 2000.

Thus, basis the given information, we have two points

(0,441300) and (8,1326720)

Slope of the linear function can be found by the formula

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{1326720-441300}{8-0}\\\\m=\frac{221355}{2}​[/tex]

Now, using the point slope form, we can find the linear function

[tex]y-y_1=m(x-x_1)\\\\y-441300=\frac{221355}{2}(x-0)\\\\y=\frac{221355}{2}x+441300[/tex]

Median salary in 2016 is

[tex]y=\frac{221355}{2}\times16+441300\\\\y=2212140[/tex]

Building an linear equation, it is found that:

  • The linear equation is [tex]y = 110677.5x + 441300[/tex]
  • The prediction for the median salary in 2016 is of $2,212,140.

-----------------------------------

A linear equation is given by:

[tex]y = mx + b[/tex]

In which m is the slope and b is the y-intercept(which is the value of y when x = 0).

-----------------------------------

In this context, the median player salary for the Dallas Cowboys in x years after 2000 is given by:

[tex]y = mx + s(0)[/tex]

In which s(0) is the median player salary in 2000.

-----------------------------------

Median salary of $441,300 in 2000 means that [tex]s(0) = 441300[/tex], and thus:

[tex]y = mx + 441300[/tex]

-----------------------------------

We have two points:

  • (0,441300)
  • (2008-2000, 1326720) = (8,1326720)
  • The slope is given by the change in y divided by the change in x.
  • Change in y: 1326720 - 441300 = 885420
  • Change in x: 8 - 0 = 8.
  • The slope is:

[tex]m = \frac{885420}{8} = 110677.5 [/tex]

Thus, the linear equation is:

[tex]y = 110677.5x + 441300[/tex]

-----------------------------------

2016 is 2016 - 2000 = 16 years after 2000, thus we have to find y when x = 16.

[tex]y(16) = 110677.5\times16 + 441300 = 2212140 [/tex]

The prediction for the median salary in 2016 is of $2,212,140.
