Answer 1

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

Brand A:
20 for $2.50
Unit Price = $2.50 / 20 = $0.125
Rounded to the hundredths place = $0.13

Brand B:
35 for $3.25
Unit Price = $3.25 / 35 = $0.092857
Rounded to the hundredths place = $0.09

Brand C:
50 for $5.25
Unit Price = $5.25 / 50 = $0.105
Rounded to the hundredths place = $0.11

Brand D:
100 for $10.00
Unit Price = $10.00 / 100 = $0.10
Rounded to the hundredths place = $0.10

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

Question 2:
