To determine which online retailer charges the least amount to buy and download 8 songs, let's analyze the cost for each retailer.
-
Online Retailer A: The line graph provides a visual representation of the cost for this retailer. Without access to the actual graph, I cannot determine the exact cost.
-
Online Retailer B: From the provided costs, for 0 to 5 songs, the cost can be assumed follows a linear pattern. For 8 songs, let's estimate by extrapolating from the available data. The cost appears to increase by $0.25 per song:
- Cost for 5 songs: $2.25
- So for 6 songs: $2.50
- For 7 songs: $2.75
- For 8 songs: $3.00
-
Online Retailer C: The cost formula is given as \(y = 0.35x + 1.5\). For 8 songs (x = 8): \[ y = 0.35(8) + 1.5 = 2.8 + 1.5 = 4.3 \]
-
Online Retailer D: The flat rate is $0.60 per song. Therefore, the cost for 8 songs would be: \[ 8 \times 0.60 = 4.8 \]
Now, comparing the costs:
- Online Retailer A: (unknown from graph)
- Online Retailer B: $3.00 (estimated)
- Online Retailer C: $4.30
- Online Retailer D: $4.80
Based on the calculations presented (without the exact data from Online Retailer A), Online Retailer B has the lowest cost for 8 songs at $3.00. Therefore, the least amount to buy and download 8 songs is from Online Retailer B.
