The school store is running low on erasers for pencils. They want to order more, so they look at the prices for 4 brands. Which one is the best buy

Question

Brand A: 20 for $2.50

Brand B: 35 for $3.25

Brand C: 50 for $5.25

Brand D: 100 for $10.00

Answer 1

To determine the best buy, we need to compare the cost per eraser for each brand.

For Brand A:
Cost per eraser = $2.50/20 = $0.125

For Brand B:
Cost per eraser = $3.25/35 ≈ $0.093

For Brand C:
Cost per eraser = $5.25/50 = $0.105

For Brand D:
Cost per eraser = $10/100 = $0.10

Considering the cost per eraser, Brand B is the best buy, as it has the lowest price per eraser.
