Final answer:
To find the price of the pizza, set up an equation using the price of the pizza and the delivery charge. Solve for the price of the pizza by combining like terms and dividing both sides of the equation.
Step-by-step explanation:
To find the price of the pizza, we need to set up an equation.
Let's assume the price of the pizza is P. The delivery charge is 12% of the price of the pizza, so it can be written as 0.12P.
The total cost, including the price of the pizza and the delivery charge, is $17.92. Therefore, the equation can be written as:
P + 0.12P = 17.92
Combining like terms, we get:
1.12P = 17.92
To solve for P, we divide both sides of the equation by 1.12:
P = 17.92 ÷ 1.12
P = 16
Therefore, the price of the pizza is $16.
