UpStudy AI · Accepted Answer

In the equation $$ c = 1.5x + 6.99 $$, the variable $$ c $$ represents the total cost in dollars, and $$ x $$ represents the number of songs downloaded.

The number $$ 1.5 $$ in this equation represents the cost per song downloaded. Specifically, it indicates that for each song Kaj downloads, she incurs an additional cost of $1.50.

To summarize:
- $$ 1.5 $$ is the cost (in dollars) for each song downloaded. 
- $$ 6.99 $$ is the fixed monthly membership fee.

Thus, the total cost $$ c $$ is calculated by adding the fixed fee to the variable cost based on the number of songs downloaded.
The number 1.5 represents the cost per song downloaded.
