Accepted Solution

A:

Answer: [tex]y=2+1.29x[/tex] Total cost to download 30 songs = $ 40.7Step-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
