The Deep Dive
The number 1.75 in the equation \( c=1.75 x+7.99 \) represents the cost per song downloaded from the streaming music service. For each song Alexandra decides to download, an additional $1.75 is added to her total monthly expense. So, the more songs she downloads, the higher her cost climbs! Now, let's say Alexandra is a music-lover who downloads a lot of songs. If she downloads 10 songs in a month, her additional cost would be \( 1.75 \times 10 = 17.50 \). Add that to the fixed membership fee of $7.99, and her total expense would come to $25.49 for the month!
