Answer 1

I don’t have the price of one pack of dry‑erase markers from your problem. Can you tell me that price?

If you want the method in the meantime:
- Total = (2 × price of one pack of markers) + $3.69.
- $3.69 rounds to $4.
- Estimated sum = (round(2 × price of markers)) + $4.
- The answer is reasonable if the exact total is close to that estimated sum.

Example: if one pack of markers is $3.19:
- 2 packs = $6.38, so total = $6.38 + $3.69 = $10.07.
- $3.69 ≈ $4 and estimated sum ≈ $6 + $4 = $10.
- The answer is reasonable because $10.07 is close to $10.

Tell me the actual marker price and I’ll fill in the blanks for your exact problem.
