Answer:

The cost of 2 pizza is:

                       $ 21

Step-by-step explanation:

It is given that:

A plain pizza costs $9.

Each topping costs $1.

Also, a group of friends ordered two pizzas.

This means that the cost of two plain pizzas will be: $ (9×2)

i.e.

Cost of two plain pizzas will be: $ 18

Also, there are three toppings in total.

(Pepperoni,mushrooms and green peppers)

This means that cost of three toppings= $ (1×3)

i.e.

Cost of three toppings=$ 3

Hence, Total cost of 2 pizza=Cost of 2 plain pizza+Cost of 3 toppings

i.e.

Total cost of 2 pizza=$ 18+$ 3

i.e.

Total cost of 2 pizza=$ 21
