The cost for 1 pencil is $

Answer 1

To find the price of one pencil, we can divide the total cost by the number of pencils for each case. Here’s how to do this for each scenario:

1. For 15 pencils at $5.55:
\[
\text{Price per pencil} = \frac{5.55}{15} = 0.37
\]

2. For 16 pencils at $5.92:
\[
\text{Price per pencil} = \frac{5.92}{16} = 0.37
\]

3. For 17 pencils at $6.29:
\[
\text{Price per pencil} = \frac{6.29}{17} = 0.37
\]

4. For 18 pencils at $6.66:
\[
\text{Price per pencil} = \frac{6.66}{18} = 0.37
\]

From all calculations, we see that the price per pencil is consistently $0.37.

Thus, the cost for 1 pencil is **$0.37**.
