To determine the cost for 1 pencil, you would need to refer to the specific table mentioned in your question. Since I don't have access to that table, I can't provide the exact cost for one pencil.
However, if the options given are:
- $9.00
- $25.00
- $4.00
- $0.25
A cost of $0.25 typically seems the most reasonable price for a single pencil.
If you have access to the table or can provide it, I could give a more accurate answer!
