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.
