Which online retailer charges the least amount to buy and download 8 songs?

Answer 1

To find out which online retailer charges the least amount to buy and download 8 songs, we need to calculate the total cost for each retailer at that quantity.

1. **Online Retailer A**: The costs are represented in a line graph. Without the specific data from the graph, we cannot determine the cost at 8 songs directly.

2. **Online Retailer B**: The costs are provided in a price list. From the provided values:
- 1 song costs $1.25
- The pattern shows an increase of $0.25 for every additional song.
To find the cost for 8 songs:
- Cost for 8 songs = Cost for 1 song + (7 x $0.25) = $1.25 + $1.75 = $3.00

3. **Online Retailer C**: The function is given by \( y = 0.35x + 1.5 \).
- For 8 songs:
\[
y = 0.35(8) + 1.5 = 2.8 + 1.5 = 4.3
\]
So, the cost for 8 songs is $4.30.

4. **Online Retailer D**: The retailer charges a flat rate of $0.60 per song.
- For 8 songs:
\[
8 \times 0.60 = 4.80
\]
So, the cost for 8 songs is $4.80.

Now, comparing the costs:
- Online Retailer A: (unknown)
- Online Retailer B: $3.00
- Online Retailer C: $4.30
- Online Retailer D: $4.80

Assuming the cost at Online Retailer A is greater than $3.00 based on typical patterns, the lowest known cost is from **Online Retailer B** with a total of $3.00 for 8 songs.

Therefore, based on the available information, **Online Retailer B** is the correct answer.
