1 answer

Let's analyze each statement based on the information provided in the table.

  1. The equation represents the relationship between the number of cupcakes baked and the total amount of sprinkles Sally used.

    • We can see from the data:
      • 6 cupcakes use 120 sprinkles.
      • 12 cupcakes use 240 sprinkles.
      • 18 cupcakes use 360 sprinkles.
    • The relationship can be described by the equation \( s = 20c \), where \( s \) is the total sprinkles and \( c \) is the number of cupcakes. Each increase of 6 cupcakes corresponds to an increase of 120 sprinkles, confirming a constant rate of 20 sprinkles per cupcake.
    • Answer: True
  2. The total amount of sprinkles Sally used is 20 times the number of cupcakes baked.

    • As derived from the relationship \( s = 20c \), for every cupcake, she uses 20 sprinkles.
    • Answer: True
  3. If Sally baked 24 cupcakes, she will have used 460 total sprinkles.

    • Using the formula \( s = 20c \):
      • For 24 cupcakes: \( s = 20 \times 24 = 480 \) sprinkles.
    • 480 is not equal to 460.
    • Answer: False

In summary:

  • 1st statement: True
  • 2nd statement: True
  • 3rd statement: False
