Q: 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?
A: 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 is 280.
Question: Carolyn buys a silverware set with 6 knives, 12 forks, and three times as many spoons as knives. Then her friend trades her 10 knives for 6 spoons. What percentage of Carolyn's silverware is knives?
Answer: First find the final number of knives Carolyn has: 10 knives + 6 knives = 16 knives. Then find the initial number of spoons Carolyn has: 6 knives * 3 spoons / knife = 18 spoons. Then find the final number of spoons Carolyn has: 18 spoons - 6 spoons = 12 spoons. Then find the total final amount of silverware Carolyn has: 12 spoons + 16 knives + 12 forks = 40 pieces. Then divide the number of knives by the total number of pieces and multiply by 100% to express the answer as a percentage: 16 knives / 40 pieces * 100% = 40%. The answer is 40.

Q: Laura wants to bake a cake for her mother. She checks the recipe and the pantry and sees that she needs to buy 2 cups of flour, 2 cups of sugar, a cup of butter, and two eggs. The flour costs $4. The sugar costs $2. The eggs cost $.5, and the butter costs $2.5. When she is done baking it, she cuts the cake into 6 slices. Her mother enjoys a piece the first two days. But on the third day, they discover that Kevin, her dog, ate the rest of the cake. How much did the amount the dog ate cost?
A: The cake cost $9 in total because 4 + 2 + .5 + 2.5 = 9. Each slice costs $1.5 because 9 / 6 = 1.5. The dog ate 4 slices because 6 - 2 = 4. The amount the dog ate cost $6 because 4 x 1.5 = 6. The answer is 6.
Question: Angela is a bike messenger in New York. She needs to deliver 8 times as many packages as meals. If she needs to deliver 27 meals and packages combined, how many meals does she deliver?
Answer:
Let p be the number of packages Angela delivers and m be the number of meals. We know that p + m = 27 and p = 8m. Substituting the second equation into the first equation, we get 8m + m = 27. Combining like terms, we get 9m = 27. Dividing both sides by 9, we get m = 3. The answer is 3.
