Jillian needs $185 for a trip. She has $65 already and saves $12 a week that she earns babysitting.

Use the Segment tool to plot a graph representing the amount of money Jillian has saved from the time she begins saving until she has saved enough for the trip.

To plot a graph representing the amount of money Jillian has saved from the beginning until she has saved enough for her trip, we can follow these steps:

  1. Determine how much more Jillian needs:

    • Jillian needs $185 and currently has $65.
    • Amount still needed = $185 - $65 = $120.

  2. Determine how many weeks it will take to save enough:

    • Jillian saves $12 each week.
    • Weeks needed = $120 / $12 = 10 weeks.

  3. Calculate the total amount saved over time:

    • At the beginning (week 0), she has $65.
    • Each week, she will add $12 to her total.
    • The amount of money Jillian has in each week can be expressed as:
      • Week 0: $65
      • Week 1: $65 + $12(1) = $77
      • Week 2: $65 + $12(2) = $89
      • Week 3: $65 + $12(3) = $101
      • Week 4: $65 + $12(4) = $113
      • Week 5: $65 + $12(5) = $125
      • Week 6: $65 + $12(6) = $137
      • Week 7: $65 + $12(7) = $149
      • Week 8: $65 + $12(8) = $161
      • Week 9: $65 + $12(9) = $173
      • Week 10: $65 + $12(10) = $185

  4. Create a table for plotting:

| Week | Total Money ($) | |------|-----------------| | 0 | 65 | | 1 | 77 | | 2 | 89 | | 3 | 101 | | 4 | 113 | | 5 | 125 | | 6 | 137 | | 7 | 149 | | 8 | 161 | | 9 | 173 | | 10 | 185 |

  1. Plotting the graph:
    • The x-axis will represent the number of weeks (from 0 to 10).
    • The y-axis will represent the total amount of money saved (from $65 to $185).
    • Plot the points corresponding to the data in the table above and connect them with a line to illustrate the increase in savings over time.

If you want to plot this graph using software or by hand, you can use the points to create a linear segment that reflects Jillian's savings growth over the specified time. The graph will show a straight line starting at $65 and sloping upwards, reaching $185 at week 10.

where should I mark it, tell me in bold words

You should mark the following points on the graph:

  • (0, 65) - This represents the amount of money Jillian has when she starts saving.
  • (1, 77) - This is the amount after 1 week of saving.
  • (2, 89) - This is the amount after 2 weeks of saving.
  • (3, 101) - This is the amount after 3 weeks of saving.
  • (4, 113) - This is the amount after 4 weeks of saving.
  • (5, 125) - This is the amount after 5 weeks of saving.
  • (6, 137) - This is the amount after 6 weeks of saving.
  • (7, 149) - This is the amount after 7 weeks of saving.
  • (8, 161) - This is the amount after 8 weeks of saving.
  • (9, 173) - This is the amount after 9 weeks of saving.
  • (10, 185) - This is the amount after 10 weeks of saving (when she has enough for the trip).

These points will help you plot the graph accurately!

Answer the question in bold words

You should mark the following points on the graph:

  • (0, 65)
  • (1, 77)
  • (2, 89)
  • (3, 101)
  • (4, 113)
  • (5, 125)
  • (6, 137)
  • (7, 149)
  • (8, 161)
