To find the unit price for each box of pencils, we need to calculate the cost per pencil in each box.
-
Box with 10 pencils at $1.50: \[ \text{Unit Price} = \frac{\text{Total Cost}}{\text{Number of Pencils}} = \frac{1.50}{10} = 0.15 \] So, the unit price for the box with 10 pencils is $0.15 per pencil.
-
Box with 25 pencils at $2.75: \[ \text{Unit Price} = \frac{\text{Total Cost}}{\text{Number of Pencils}} = \frac{2.75}{25} = 0.11 \] So, the unit price for the box with 25 pencils is $0.11 per pencil.
In summary:
- Box with 10 pencils: $0.15 per pencil
- Box with 25 pencils: $0.11 per pencil
