Daria consumes 2.5 times the amount of pizza that Don does. If Don eats 80 pizzas, how many pizzas do they both eat altogether? Let's be accurate as possible.
Since Daria consumes two and a half times the amount of pizza that Don does, if Don eats 80 pizzas, Daria eats 2.5 * 80 = 200 pizzas. Together, they eat 200 + 80 = 280 pizzas.
The answer: 280.
