.

Answer 1

To find the cost of one pencil, we can use the total cost for any given number of pencils and divide it by that number.

Let's use the data provided:

1. For 9 pencils: \[ \text{Cost per pencil} = \frac{3.24}{9} = 0.36 \]

2. For 10 pencils: \[ \text{Cost per pencil} = \frac{3.6}{10} = 0.36 \]

3. For 11 pencils: \[ \text{Cost per pencil} = \frac{3.96}{11} = 0.36 \]

4. For 12 pencils: \[ \text{Cost per pencil} = \frac{4.32}{12} = 0.36 \]

In each case, we find that the cost for 1 pencil is \( $0.36 \).

Thus, the cost for 1 pencil is \( \boxed{0.36} \).
