1. You can call to the cost of each one of Tanya's items and to the cost of each one of Tony's items.
2. Based on the information given in the problem and knowing that both paid the same amount of money, you can write the following expression:
3. You must solve for :
4. The total amount of money that Tanya and Tony paid was:
dollars
5. Therefore, the amount of money that Tony paid for each item was:
dollars
The answer is: The individual cost of each Tanya's items is dollars and the individual cost of each Tony's items is dollars.

Step-by-step explanation:
Total number of songs is
And out of 47, total number's of katy Pery's songs are 17.
So probability that the next song will be the song of Katy Pery is
And therefore probability that the next song is not of Kety's pary's song is
And that's the required answer .
Answer:
Option d is correct.
no , because y does not vary directly with x.
Step-by-step explanation:
Direct variation states that a relationship between any two variables in which one is a constant multiple of the other.
in other way, when one of the variable changes then the other changes in proportion to the first.
If y is directly proportional to x i.e,
then the equation is of the form;
where k is the constant of Variation.
From the table:
Consider any values of x and y:
Let x = 4 and y = 28
then by definition of direct variation solve for k;
28 = 4k
Divide both sides by 4 we get;
k = 7
Then the equation become: y = 7x .....[1]
Check whether the other data follows this equation or not,
x = 6 and y = 48
Substitute in equation [1];
48 = 7(6)
48 = 42 False
Also, for;
x = 8 and y= 72
72 = 7(8)
72 = 56 False
⇒ y= 7x does not follows the data of the given table.
Therefore, y does not vary directly with x.
Answer is
