To determine the cost of 1 pencil, we can use the cost of the quantity for which we have the data. Let's take the 12 pencils as an example:
The cost for 12 pencils is $3.00.
To find the cost of 1 pencil, we divide the total cost by the quantity:
Cost of 1 pencil = Total cost / Quantity = $3.00 / 12 = $0.25
Therefore, the cost for 1 pencil is $0.25.
