An online music club has one-time registration fee of $20 and charges $0.50 for each song download. If ella has $50.00 to join the club and buy songs, which inequality gives the maximum number of songs, s, she can buy? s ≥ 30 s ≤ 30 s ≥ 60 s ≤ 60

To find the maximum number of songs Ella can buy, we need to subtract the registration fee from her initial budget and then divide the remaining amount by the cost per song.

Ella's initial budget is $50.00.
The registration fee is $20.00.
So, after paying the registration fee, Ella has $50.00 - $20.00 = $<<50-20=30.00>>30.00 left.
Each song costs $0.50.
Thus, the maximum number of songs Ella can buy is $30.00 / $0.50 = <<30/0.5=60>>60.

Therefore, the correct inequality is s ≤ 60.
