Question: A married couple and their 6 children are ordering some pizza. If the couple want 3 slices each and the children want 1 slice each, how many 4-slice pizzas should they order?
Answer: Step-by-step reasoning process: The couple want 3 slices each for a total of 2 * 3 = 6 slices. The children want 1 slice each for a total of 1 * 6 = 6 slices. They want 6 + 6 = 12 slices in total. Each pizza has 4 slices so they need 12 / 4 = 3 pizzas.
So the answer is 3.

Question: Arthur has $200 in his wallet. He spends four-fifths of that. How much does he have left?

Question: John decides to buy utensils. They come in 30 packs with an equal number of knives, forks, and spoons. How many packs does he need to buy if he wants 50 spoons?

Question: 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?
Answer:
Step-by-step reasoning process: 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.
So the answer is 280.
