Question

An online music store is offering a promotion. When you spend $45 or more, you receive 3 songs for free. You buy an album for $15. Identify the inequality that represents how much more money m you must spend to receive the three free songs.

Answer 1

Answer: x ≥ $30.

Where x is the amount of money that you need to spend if you want to have the 3 free songs.

Explanation:

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

You already bought an album that costs $15, then the minimum amount that you need to spend is (when you spend exactly $45):

$45 - $15 = x = $30.

Then the inequality is:

x ≥ $30.

Because if you spend more than $45 you also get the songs.
