The Correct Answer and Explanation is:
The cost of 12 pencils is $2.40, and we need to find the price per pencil.
To find the unit price, we divide the total cost by the number of pencils. This calculation is:Unit Price=Total CostNumber of Pencils=2.4012=0.20\text{Unit Price} = \frac{\text{Total Cost}}{\text{Number of Pencils}} = \frac{2.40}{12} = 0.20Unit Price=Number of PencilsTotal Cost=122.40=0.20
Thus, the unit price per pencil is $0.20.
The correct answer is A. $0.20.
Explanation:
- The total price for 12 pencils is $2.40.
- To find the price of one pencil (unit price), divide the total price by the number of pencils: 2.4012=0.20\frac{2.40}{12} = 0.20122.40=0.20
- This means each pencil costs $0.20.
This method of dividing the total cost by the number of items is commonly used when calculating unit prices.
