Question

A music app charges $5 to download the app plus $1.20 per song downloaded. Write and solve alinear equation to find the total cost to download 35 songs on this app. $47 $42$40.70$34

Answer 1

Let x be the number of songs and y be the total cost. Then, we can write,

`y=1.20x+5`

Now, we need the total cost for 35 download songs. By substituting x=35 into the line equation, we get

`y=1.20(35)+5`

which gives

`\begin{gathered} y=42+5 \\ y=47 \end{gathered}`

Therefore, the answer is $47.
