Let's break down the information given in the problem to form the inequality.
- Let \( a \) be the number of playlists on Ashley's app.
- The number of playlists on Liam's app is \( 4a \).
- The combined total of playlists is at least 45.
We can express the total number of playlists as follows: \[ a + 4a \geq 45 \] This simplifies to: \[ 5a \geq 45 \]
So, the inequality that can be used to determine the number of playlists in Ashley's app is: 5a ≥ 45
For Question 2, since Ashley’s app has 9 playlists, we can state that it has at least 9 playlists, but given the context of what you've asked, if you're looking for how many playlists would fit the condition of Question 1, we would also say that she has at least that number according to the inequality.
So if phrasing it in context, you would say: "Ashley's app has at least 9 playlists."
