To determine which online retailer charges the least amount to buy and download 8 songs, let's analyze the pricing given for each retailer.
1. **Online Retailer A**: From the given information, A charges $1 for 2 songs. Therefore, for 8 songs:
\[
\text{Cost for 8 songs} = \frac{8}{2} \times 1 = 4 \text{ dollars}
\]
2. **Online Retailer B**: The prices are incremented for each song. From the provided list:
- 1 song costs $1.00
- 2 songs cost $1.25
- 3 songs cost $1.50
- 4 songs cost $1.75
- 5 songs cost $2.00
- 6 songs cost $2.25
- 7 songs cost $2.50
- 8 songs cost $2.75
So, the cost for 8 songs is $2.75.
3. **Online Retailer C**: The cost function is given by the equation \( y = 0.35x + 1.5 \). To find the cost for 8 songs:
\[
y = 0.35(8) + 1.5 = 2.8 + 1.5 = 4.3 \text{ dollars}
\]
4. **Online Retailer D**: charges a flat rate of $0.60 for each song. Therefore, for 8 songs:
\[
\text{Cost for 8 songs} = 8 \times 0.60 = 4.8 \text{ dollars}
\]
Now, let's summarize the total costs for 8 songs from each retailer:
- Online Retailer A: $4.00
- Online Retailer B: $2.75
- Online Retailer C: $4.30
- Online Retailer D: $4.80
