To find the unit price for each box, we can divide the total cost of each box by the number of pencils in that box.
For the 10 count box:
- Cost: $1.50
- Number of pencils: 10
Unit price for the 10 count box: \[ \text{Unit price} = \frac{1.50}{10} = 0.15 \]
For the 25 count box:
- Cost: $2.75
- Number of pencils: 25
Unit price for the 25 count box: \[ \text{Unit price} = \frac{2.75}{25} = 0.11 \]
So, the unit prices are:
- The 10 count box is $0.15/pencil.
- The 25 count box is $0.11/pencil.
