Answer:

Step-by-step explanation:
represent price per video game.
represent demand.
The linear equation in slope intercept form can be represented as:

where
is slope of line or rate of change of demand of game per dollar change in price and
is the y-intercept or initial price of game.
We can construct two points using the data given.
When price was $66 each demand was 400. 
When price was $36 each demand was 1300. 
Using the points we can find slope
of line.




Using point slope form of linear equation to write the equation using a given point.

Using point
.

⇒
[Using distribution]
Adding 400 to both sides:
⇒ 
⇒
The linear relationship between price and demand can be written as:

Answer:
6
Step-by-step explanation:
3(x+2)=24
3x+6=24
-6 -6
<u>3x=18</u>

x=6
By definition we have that the average rate of change of the function is:

Evaluating the function for the complete interval we have that the AVR is given by:

Rewriting we have:

Simplifying the expression we have:


Answer:
the average rate of change of the function defined by the table is:
