Three friends, Brody, Avery, and Khalil are saving different amounts of money each week. Brody started with $27 and added $20 every week. Avery's savings are represented by the table below, and Khalil's savings are represented by the graph below.

To compare the amounts saved by Brody, Avery, and Khalil per week, we need to analyze their savings:

1. Brody:

   • Starting amount = $27
   • Amount added per week = $20
   • Therefore, Brody saves $20 per week.

2. Avery:

   • From the table provided, we can calculate how much Avery saves each week by finding the difference in total savings week by week:
     • From week 4 ($56) to week 8 ($76): $76 - $56 = $20
     • From week 8 ($76) to week 12 ($96): $96 - $76 = $20
     • From week 12 ($96) to week 16 ($116): $116 - $96 = $20
   • Therefore, Avery also saves $20 per week.

3. Khalil:

   • Given the points (2, $69) and (4, $99), we can find Khalil's savings per week by calculating the change in total savings divided by the change in weeks:
     • Savings difference: $99 - $69 = $30
     • Weeks difference: 4 - 2 = 2
     • Therefore, Khalil saves $30 / 2 = $15 per week.

Now, to summarize the weekly savings:

• Brody: $20 per week
• Avery: $20 per week
• Khalil: $15 per week

Sorting from least to greatest dollar amount saved per week:

1. Khalil: $15
2. Brody: $20
3. Avery: $20

Final order: Khalil, Brody, Avery (Khalil < Brody = Avery).
