To find the cost of a large pizza with 3 additional toppings, you can use the equation:
\[ y = 11 + 1.5x \]
Where:
- \( y \) is the total price of the pizza.
- \( x \) is the number of additional toppings.
In this case, the number of additional toppings \( x \) is 3.
Now, plug in the value of \( x \):
\[ y = 11 + 1.5(3) \]
Calculate it step by step:
-
Calculate the cost of the toppings: \[ 1.5 \times 3 = 4.5 \]
-
Add that to the base price of the pizza: \[ y = 11 + 4.5 = 15.5 \]
Therefore, the cost of a large pizza with 3 toppings is $15.50.
