To model the cost of the ice cream sundae with toppings, let's break it down:
- The base cost of a plain ice cream sundae is $4.
- Each topping costs an additional $1, and you can choose up to 10 toppings.
Let's denote:
-
\( x \) = number of toppings (where \( 0 \leq x \leq 10 \))
-
The total cost \( C \) can be expressed as:
\[ C = 4 + x \]
This means:
- If no toppings are chosen (x = 0), the cost is $4.
- If all 10 toppings are chosen (x = 10), the cost is \( 4 + 10 = 14 \).
The graph representing this would be a straight line starting at the point (0, 4) on the y-axis and going up to the point (10, 14) on the graph. The slope of the line represents the additional $1 for each topping.
So, the correct graph to represent the cost would:
- Start at (0, 4) and end at (10, 14).
- Be a straight line.
Please look for a graph that meets these criteria.
