Answer: [tex]y=2+1.29x[/tex]

Total cost to download 30 songs = $ 40.7

Step-by-step explanation:

Given : A music app charges $2 to download the app plus $1.29 per song downloaded.

Then the total cost = Charge to download app + price per song x (No. of songs)        (1)

Let x be the number of songs and y be the total cost ( in dollars).

Then, we have the following equation ,

[tex]y=2+1.29(x)[/tex]  [Substitute values in (1)]

i.e. Required linear equation = [tex]y=2+1.29x[/tex]

At x= 30 , we have

[tex]y=2+1.29(30)=2+38.7=40.7[/tex]

Hence, the total cost to download 30 songs = $ 40.7

Answer:

Total cost to download 30 songs is [tex]\$40.7[/tex].

Step-by-step explanation:

Given: A music app charges [tex]\$2[/tex] to download the app plus [tex]\$1.29[/tex] per song downloaded.

Let the number of songs downloaded be [tex]x[/tex].

Now according to question,

Total cost of songs [tex]=[/tex] charge to download music app [tex]+[/tex] number of songs downloaded [tex]\times[/tex] cost of per song downloaded

                                [tex]=\$2\ +\ \$1.29 \times x[/tex]

Therefore, total cost of 30 songs [tex]=\$2\ +\ \$1.29\times 30[/tex]

                                                       [tex]=\$2 + \$38.7\\=\$ 40.7[/tex]

Hence, Total cost to download 30 songs is [tex]\$40.7[/tex].
