1. **State the problem:** A bank charges a monthly fee of 3.50 for a checking account with an initial balance of 32. We want to find how many months it takes for the balance to become negative.
2. **Set up the formula:** Let $n$ be the number of months. The balance after $n$ months is given by:
$$\text{Balance} = 32 - 3.50n$$
3. **Find when the balance is negative:** We want:
$$32 - 3.50n < 0$$
4. **Solve the inequality:**
$$32 < 3.50n$$
Divide both sides by 3.50:
$$\frac{32}{\cancel{3.50}} < \frac{3.50n}{\cancel{3.50}}$$
$$\frac{32}{3.50} < n$$
5. **Calculate the value:**
$$n > \frac{32}{3.50} = 9.142857...$$
6. **Interpret the result:** Since $n$ must be an integer number of months, the balance becomes negative after more than 9.14 months, so at the 10th month.
**Final answer:** It will take 10 months for the account to have a negative balance.
