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.
