Answer 1

To determine the unit price of each brand of erasers, you can divide the total price by the number of erasers for each brand.

1. Brand A:

   • Total price: $2.50
   • Number of erasers: 20
   • Unit price = $2.50 / 20 = $0.125
   • Rounded unit price = $0.13 per eraser

2. Brand B:

   • Total price: $3.25
   • Number of erasers: 35
   • Unit price = $3.25 / 35 = $0.092857
   • Rounded unit price = $0.09 per eraser

3. Brand C:

   • Total price: $5.25
   • Number of erasers: 50
   • Unit price = $5.25 / 50 = $0.105
   • Rounded unit price = $0.11 per eraser

4. Brand D:

   • Total price: $10.00
   • Number of erasers: 100
   • Unit price = $10.00 / 100 = $0.10
   • Rounded unit price = $0.10 per eraser

Now, let's summarize the unit prices:

• Brand A: $0.13 per eraser
• Brand B: $0.09 per eraser
• Brand C: $0.11 per eraser
• Brand D: $0.10 per eraser
