Answer:

When you spend $45 or more, you get 3 free songs.

You already spent $15.

Then, if we define m as the amount that you need to spend in order to get the 3 free songs, the minimum value of m will be such that you spend exactly $45 in total.

$15 + m = $45.

But if you spend more than $45 you also get the songs, so the inequality that represents this situation is:

$15 + m ≥ $45.

2)Solving the equation for m we have:

m ≥ $45 - $15 = $30

m ≥ $30.

So the minimum amount that you can spend in order to get the songs is when the equality is true, this means that:

m = $30 is the minimum that you must spend if you want the 3 free songs.
