A large pizza has a diameter of 35cm. Two large pizza costs $19.99. A medium pizza has a diameter of 30cm. Three medium pizzas costs $24.99. Which is the better deal: 2 large pizzas or 3 medium pizzas? Justify your answer.

3 medium pizza because for the large in the unit rate is 9.99 and for the medium pizza the unit rate is 8.33 and for the 2 large if you add 35 + 35=70cm and for three medium pizza if u add 30+30+30=90cm so either way you will get a cheaper price and still have a greater amount than two large pizzas

I recommend the large because of its costs cheaper.
