The proportional relationship between the number of songs Joseph downloads, \( s \), and the total cost in dollars and cents, \( c \), can be represented by the equation \( c=0.2 s \). How much does it cost to download a single song?

The cost to download a single song can be easily found by looking at the equation \( c = 0.2s \). Since \( c \) represents the total cost and \( s \) represents the number of songs, when \( s = 1 \), then \( c = 0.2(1) = 0.2 \). This means that it costs 20 cents to download a single song! Now, if you're a music lover who finds yourself downloading a lot of tunes, think about how this adds up! If you were to download 10 songs, for example, that would only cost you $2! That's a super affordable way to build your music library while managing expenses.
