To determine the cost for 1 pencil, we can take the cost for a known quantity of pencils and divide by that quantity.
Using the 12 pencils as an example:
- Cost for 12 pencils: $3.00
Now, we find the cost for 1 pencil by dividing the total cost by the quantity:
\[ \text{Cost per pencil} = \frac{\text{Total Cost}}{\text{Quantity}} = \frac{3.00}{12} = 0.25 \]
Thus, the cost for 1 pencil is $0.25.
