1 answer

To determine the price of one pencil, you can divide the total cost by the number of pencils for any of the given entries.

Let's calculate the price per pencil using the first two entries:

  1. For 6 pencils costing $2.4: \[ \text{Price per pencil} = \frac{\text{Total Cost}}{\text{Number of pencils}} = \frac{2.4}{6} = 0.4 \]

  2. For 7 pencils costing $2.8: \[ \text{Price per pencil} = \frac{2.8}{7} = 0.4 \]

  3. For 8 pencils costing $3.2: \[ \text{Price per pencil} = \frac{3.2}{8} = 0.4 \]

  4. For 9 pencils costing $3.6: \[ \text{Price per pencil} = \frac{3.6}{9} = 0.4 \]

In each case, the price per pencil is consistent.

Thus, the price for 1 pencil is $0.40.
