To find the unit price per pencil, we will follow the steps provided:
1. Determine how many pencils are in a dozen:
- 1 dozen = 12 pencils
- 2 dozen = 24 pencils
2. Calculate the total number of pencils in 20 dozen:
- 20 dozen = 20 × 12 pencils = 240 pencils
3. Now we calculate the unit price by dividing the total cost of the box by the total number of pencils:
- Total cost of the box = $1.35
- Number of pencils = 240
Unit price = Total cost / Number of pencils
Unit price = $1.35 / 240
4. Now we calculate this division:
- $1.35 ÷ 240 = $0.005625
5. Round this to the hundredths place:
- $0.005625 rounds to $0.01 when rounded to the nearest hundredths (2 digits after the decimal).
Finally, the unit price is **$0.01** per pencil.

- Number of pencils = 240
Unit price = Total cost / Number of pencils
Unit price = $1.35 / 240

- $1.35 ÷ 240 = $0.005625

To determine the unit price of each brand, we'll calculate the price per eraser for each brand and then round the result to the hundredths place.
### Brand A
- 20 erasers for $2.50
- Unit price = Total cost / Number of erasers = $2.50 / 20 = $0.125
- Rounded to the hundredths place: **$0.13**
### Brand B
- 35 erasers for $3.25
- Unit price = $3.25 / 35 = $0.092857
- Rounded to the hundredths place: **$0.09**
### Brand C
- 50 erasers for $5.25
- Unit price = $5.25 / 50 = $0.105
- Rounded to the hundredths place: **$0.11**
### Brand D
- 100 erasers for $10.00
- Unit price = $10.00 / 100 = $0.10
- Rounded to the hundredths place: **$0.10**
### Summary of 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
### Best Buy

**The best buy is Brand B at $0.09 per eraser.**
Thus, the answer is **b. brand b**.
