Answer 1

I don’t have the first addend (the other cost) needed to fill the blanks. Can you tell me that amount?

Meanwhile, here’s how to complete the sentence and check reasonableness when you have the other cost:

Steps:
1. Exact total = (other cost) + $3.69.
2. Round $3.69 to $4.
3. Round the other cost to the nearest dollar and add that to $4 to get the estimated sum.
4. If the exact total is close to the estimated sum (typically within about $1), then the answer is reasonable.

Example: if the other cost were $7.28:
- Exact total = $7.28 + $3.69 = $10.97.
- $3.69 is about $4.
- Round $7.28 to $7; estimated sum ≈ $7 + $4 = $11.
- The answer is reasonable because $10.97 is close to $11.

Tell me the other cost and I’ll fill in the blanks for your problem.
