To find out which online retailer charges the least amount to buy and download 8 songs, let's calculate the cost for each retailer.
Online Retailer A: The line graph is not provided, but you would typically read the cost for 8 songs from the graph.
Online Retailer B: From the table for Online Retailer B:
- Cost for 2 songs: $1.00
- Cost for 3 songs: $1.75
- Cost for 4 songs: $2.00
- Cost for 5 songs: $2.25
We can extrapolate the costs for 6, 7, and 8 songs (not directly available from the table):
- Continuing the pattern indicated, the incremental cost per additional song appears to be $0.25.
- Thus:
- Cost for 6 songs: $2.50 (increment of $0.25 from 5 songs)
- Cost for 7 songs: $2.75 (increment of $0.25 from 6 songs)
- Cost for 8 songs: $3.00 (increment of $0.25 from 7 songs)
Total for 8 songs: $3.00
Online Retailer C: The cost function is given as \(y = 0.35x + 1.5\). Plugging in \(x = 8\) (for 8 songs): \[ y = 0.35(8) + 1.5 = 2.8 + 1.5 = 4.3 \] Total for 8 songs: $4.30
Online Retailer D: The flat rate is $0.60 to download a song. For 8 songs: \[ 0.60 \times 8 = 4.80 \] Total for 8 songs: $4.80
Now let's summarize:
- Online Retailer A: Cost is unknown from the graph.
- Online Retailer B: $3.00
- Online Retailer C: $4.30
- Online Retailer D: $4.80
Without the cost from Online Retailer A, we can conclude that based solely on the information given for the other retailers, Online Retailer B charges the least amount at $3.00 for downloading 8 songs.
