he local ice cream shop offers a deal on Wednesday where you can pay $4 for a plain ice cream sundae and $1 per topping you choose (maximum of 10 toppings). Which of the following graphs best models the cost someone could pay using this offer? (1 point) Responses

To model the cost of an ice cream sundae at the local ice cream shop based on the given pricing structure, we can establish a mathematical function.

The cost of the sundae can be formulated as:

\[ \text{Cost} = 4 + x \]

where \( x \) represents the number of toppings chosen (with a maximum of 10 toppings).

This means:

  • If no toppings are chosen (\( x = 0 \)), the cost is \( 4 + 0 = 4 \).
  • If one topping is chosen (\( x = 1 \)), the cost is \( 4 + 1 = 5 \).
  • If two toppings are chosen (\( x = 2 \)), the cost is \( 4 + 2 = 6 \).
  • Continuing this pattern, if the maximum of 10 toppings is chosen (\( x = 10 \)), the cost is \( 4 + 10 = 14 \).

The scenario can be represented on a graph:

  • The x-axis would represent the number of toppings (0 to 10).
  • The y-axis would represent the total cost (in dollars).

The relationship is linear, starting at \( (0, 4) \) and moving up to \( (10, 14) \). The graph would be a straight line with a slope of 1 (since each topping costs an additional $1).

Given this information, the best graph that represents this situation would be a linear graph that starts at point \( (0, 4) \) and rises to point \( (10, 14) \). If you provide the graphs to choose from, I can help identify which one matches this description.
