To determine the maximum number of songs, \( s \), that Tiffany can purchase as a member of the online music club, we need to set up an inequality based on her budget.
Tiffany has $50 to spend. The one-time registration fee is $20, leaving her with \( 50 - 20 = 30 \) dollars to spend on song downloads. Each song download costs $0.50. Therefore, the total cost for \( s \) song downloads is \( 0.50s \).
The inequality can be set up as follows:
\[ 20 + 0.50s \leq 50 \]
Thus, the correct inequality that may be used to determine the maximum number of songs is:
20 + 0.50s ≤ 50
For Question 2, we need to solve this inequality to find how many songs Tiffany can download:
\[ 20 + 0.50s \leq 50 \] Subtract 20 from both sides:
\[ 0.50s \leq 30 \] Divide both sides by 0.50:
\[ s \leq 60 \]
Tiffany can download at most 60 songs.
