Let's analyze the plans to determine the truth of each statement provided.
-
Plan 1 will always cost more than Plan 2.
- Not true. Plan 1 has a flat fee of $7 and costs $2.50 per video viewed, while Plan 2 costs $4 per video viewed. Depending on the number of videos viewed, Plan 1 can be cheaper than Plan 2. For example, if you view 1 video, Plan 1 costs $9.50 and Plan 2 costs $4. If you view enough videos, Plan 1 can become cheaper.
- Response: False
-
Plan 1 is nonproportional and Plan 2 is proportional.
- True. Plan 1 has a fixed monthly fee plus a variable cost based on the number of videos viewed, making it nonproportional. Plan 2 charges only based on the number of videos viewed, which is a proportional relationship.
- Response: True
-
You would have to view at least 5 videos for Plan 1 to be cheaper than Plan 2.
-
Not true. To determine the break-even point between the two plans, you can set up an equation:
- Plan 1: $7 + $2.50x
- Plan 2: $4x
Setting them equal: 7 + 2.50x = 4x
This simplifies to: 7 = 4x - 2.50x 7 = 1.50x x = 7 / 1.50 = 4.67
Since you cannot view a fraction of a video, you would need to view 5 videos for Plan 1 to be less than Plan 2; thus this statement is true.
- Response: True
-
-
This is a good graph for the scenario.
- Without seeing the graph, I cannot determine if it is accurate or not. However, a good graph would display the cost of both plans as a function of the number of videos viewed and show the point where they intersect. This statement remains indeterminate without additional information.
- Response: (Leave this one blank or indicate you cannot assess without the graph.)
To summarize:
- Plan 1 will always cost more than Plan 2: False
- Plan 1 is nonproportional and Plan 2 is proportional: True
- You would have to view at least 5 videos for Plan 1 to be cheaper than Plan 2: True
- This is a good graph for the scenario: (indeterminate or blank)
