Price per pizza = total cost / # of pizzas
Price per pizza = $180 / 9 pizzas
Price per pizza = $20 per pizza

Price of any number of pizzas = Price per pizza * # of pizzas
Price of 15 pizzas = $20 * 15
Price of 15 pizzas = $300

Hope this helps! :)

If 9 pizzas cost $180, but we want to find out how much 15 pizzas would cost.

First, you want to figure out how much each pizza cost, we know that 9 pizzas cost $180.

180 ÷ 9 = 20

$20.00 per pizza.

Now that we know that each pizza cost $20, we just have to multiply the $20.00 and 15.

20 x 15 = 300

So, 15 pizza would cost $300.00

Hope this helps. :)
