Explanation:

Step1: Calculate cost for 50 songs

Monthly - base cost is $13 and cost per - song is $0.50. For 50 songs, cost of songs is $0.50\times50$. Then add base cost.
$13 + 0.50\times50$

Step2: Simplify the expression for 50 songs

$13+25 = 38$

Step3: Calculate cost for s songs

The base cost is $13 and cost per - song is $0.50. So the total cost for s songs is the sum of the base cost and the cost of s songs.
$13 + 0.50s$

Cost with 50 songs: $38
Cost with s songs: $13 + 0.50s
