Let's analyze the equation \( s = 110.5m \) to answer both parts of your question.

**Part A: Which statement is true about the given equation?**

To determine a true statement from the options:

1. **\( A: After 5 months, she has $552.50 saved. \)**
- If we calculate: \( s = 110.5 \times 5 = 552.5 \).
- This statement is **true**.

2. **\( A: After 4 months, she has $552.50 saved. \)**
- Calculate: \( s = 110.5 \times 4 = 442 \).
- This statement is **false**.

3. **\( A: After 5 months, she has $110.50 saved. \)**
- This is **false** since after 5 months, she has $552.50.

4. **\( A: She puts $100.50 in her savings account every 5 months. \)**
- This is **false** as she deposits $110.50 every month.

5. The correct statement is:
- **\( A: After 5 months, she has $552.50 saved. \)**

**Part B: How long will it take Tanna to save $1,215.50?**

To find out how many months it will take for her to reach that amount:
- Set \( s = 1215.50 \):
\[
1215.50 = 110.5m
\]
Now, solve for \( m \):
\[
m = \frac{1215.50}{110.5} = 11
\]

Therefore, it will take **11 months** for Tanna to save $1,215.50.

### Final Answers:
**Part A: A: After 5 months, she has $552.50 saved.**
**Part B: B: 11 months.**
