Sheila is ordering pizzas for a party. each plain pizza costs $9.00, and each topping costs $1.50. the delivery charge is $3.00. write a function rule to show the total cost of the pizzas if the pizza ordered has 2 toppings. how much will 5 pizzas cost?

, where c is the total cost of x pizzas.

The cost of 5 pizzas = $63

Step-by-step explanation:

Given : Cost of each pizza = $9.00

Cost of each topping =  $1.50

⇒ Cost of 2 toppings =  2 x $1.50 = $3.00

Then, the cost of each pizza having 2 toppings =  $9.00+  $3.00=  $12.00

Let x be the number of pizzas .

Then , the cost of x pizzas = 12x

Since , Delivery charge =  $3.00

Then, the total cost of ordering x pizzas( in dollars) =  Cost of x pizzas+ Delivery charge = 12x+3

Function rule to show the total cost of the pizzas if the pizza ordered has 2 toppings : , where c is the total cost.

Put x= 5

Hence, the cost of 5 pizzas = $63

each side has a different length.
