An online music is charging $25 for 100 downloads and an additional $1.50 for every download over 100. write an equation that could be used to determine the total cost, c, for downloading , d, number of songs over 100.

Step-by-step explanation:

Let c represent the total cost and d represent the number of downloaded songs over 100. Therefore, the corresponding equation is:

For example, if we downloaded 150 songs, we would expect the cost to be $25 plus $1.50 each for 50 songs: $25 + ($1.50 × 50) = $25 + $75 = $100.

We can verify by substituting 50 for d in our equation:
