Alonso Sheppard · Answer 1

In constructing an inequality, you need to know the following:

1. What don't we know? How many songs can be bought? So, let x be the numbers of songs.

2. What do we know? Each songs costs $2 plus a fee for using the artist's site of $5.

3. Is there more than 1 possible solution? Yes, because there is enough money left if she only bought 1 song.

The meaning of no more than $40 means it must not exceed $40, $40 or less, or only $40.

So, song + fee can't be more than $40 and song + fee could equal to $40.

Therefore, song + fee for using an artist's site less than or equal to $40.

Final Answer: 2x+5 < = 40
