1. **State the problem:** We need to find the weekly savings rate for Brody, Avery, and Khalil, then order them from least to greatest savings per week.
2. **Brody's savings:** Brody started with $27 and adds $20 every week. So, his weekly savings rate is $20$.
3. **Avery's savings:** From the table, savings increase as weeks increase. Calculate the weekly rate using two points, for example, weeks 4 and 8:
$$\text{Rate} = \frac{76 - 56}{8 - 4} = \frac{20}{4} = 5$$
So Avery saves $5$ dollars per week.
4. **Khalil's savings:** From the graph, two points are given: (2, 69) and (4, 99). Calculate the slope (weekly savings rate):
$$\text{Rate} = \frac{99 - 69}{4 - 2} = \frac{30}{2} = 15$$
So Khalil saves $15$ dollars per week.
5. **Order from least to greatest weekly savings:** Avery ($5$), Khalil ($15$), Brody ($20$).
**Final answer:** Avery, Khalil, Brody
