To determine the best buy, we need to calculate the price per eraser for each brand.
For Brand A: $2.50 / 20 erasers = $0.125 per eraser
For Brand B: $3.25 / 35 erasers = $0.093 per eraser
For Brand C: $5.25 / 50 erasers = $0.105 per eraser
For Brand D: $10.00 / 100 erasers = $0.10 per eraser
The best buy is Brand B, which has a price of $0.093 per eraser.
