The cost for 1 pencil is $

Answer 1

To find the price for one pencil, we can take the total cost for each number of pencils and divide it by the number of pencils.

Here’s the breakdown for each case provided:

1. For 5 pencils: \[ \text{Cost per pencil} = \frac{2.6}{5} = 0.52 \]

2. For 6 pencils: \[ \text{Cost per pencil} = \frac{3.12}{6} = 0.52 \]

3. For 7 pencils: \[ \text{Cost per pencil} = \frac{3.64}{7} = 0.52 \]

4. For 8 pencils: \[ \text{Cost per pencil} = \frac{4.16}{8} = 0.52 \]

In all cases, the cost per pencil is consistent at $0.52.

Therefore, the cost for 1 pencil is $0.52.
