Answer:
2
Step-by-step explanation:
<em>for </em><em>this </em><em>question</em><em> </em><em>you've </em><em>to </em><em>cross </em><em>multiply</em>
<em>-</em><em>2</em><em>2</em><em>/</em><em>9</em><em>r</em><em>=</em><em>1</em><em>1</em><em>/</em><em>9</em>
<em>9</em><em>9</em><em>r</em><em>=</em><em>-</em><em>1</em><em>9</em><em>8</em>
<em>then </em><em>you </em><em>divide</em><em> both</em><em> sides</em><em> by</em><em> </em><em>9</em><em>9</em><em> </em><em>inorder </em><em>to </em><em>remain </em><em>with </em><em>r </em><em>on </em><em>one </em><em>side</em>
<em>9</em><em>9</em><em>r</em><em>/</em><em>9</em><em>9</em><em>=</em><em>1</em><em>9</em><em>8</em><em>/</em><em>9</em><em>9</em>
<em>r=</em><em>2</em>
<em>I </em><em>hope </em><em>this </em><em>helps</em>
Answer:
Step-by-step explanation:
The given relations between numbers and prices can be used to write a system of equations for the number of each kind of ticket. One equation will describe ticket numbers; the other will describe ticket revenue.
<h3>Setup</h3>
Let x represent the number of adult tickets, and y the number of student tickets. The given relations can be written as the general-form equations ...
8x -y -11 = 0 . . . . . . . . . ticket numbers
5x +3y -895 = 0 . . . . . ticket revenue
<h3>Solution</h3>
The setup using general form equations lends itself to solution using the "cross multiplication method." Using this method, we define three numbers used in the solution:
Δ = 8(3) -5(-1) = 24 +5 = 29
Δx = -1(-895) -3(-11) = 895 +33 = 928
Δy = -11(5) -(-895)(8) = -55 +7160 = 7105
And the solutions are ...
x = Δx/Δ = 928/29 = 32
y = Δy/Δ = 7105/29 = 245
32 adult tickets and 245 student tickets were sold.

From the table we can see:
Number of songs: Cost:
0 $ 0
1 $1.25
2 $2.50
3 $3.75
4 $5.00
Therefore the rate of change is: (2.50 - 1.25) / ( 2 - 1 ) = $1.25
Answer:
It means that : C. The cost increases $1.25 for each additional song that is downloaded.
