Question

Liem orders a large pizza. The pizza store charges $11.00 for the pizza with cheese and $1.50 for each additional topping. The mathematical equation for the function is y=11+1.5x, with x representing the number of additional toppings and y representing the total price of the pizza. What is the cost of a large pizza with 3 toppings?

Answer 1

To find the total cost of a large pizza with 3 additional toppings using the equation \( y = 11 + 1.5x \), you need to substitute \( x \) with 3 (since \( x \) represents the number of additional toppings).

\[ y = 11 + 1.5(3) \]

Now, calculate \( 1.5 \times 3 \):

\[ 1.5 \times 3 = 4.5 \]

Now substitute that back into the equation:

\[ y = 11 + 4.5 \]

Now add \( 11 + 4.5 \):

\[ y = 15.5 \]

So, the cost of a large pizza with 3 toppings is $15.50.
