Because it is cheaper to buy the packs of 5, the teacher should satisfy the 11 students who want the vampire theme with 2 packs of 5 and 1 individual bag. This will cost the teacher 2 * 3 + 1 * 1 = $7. Similarly, the 14 students who want a pumpkin - themed bag can be satisfied by 2 packs of 5 and 4 individual bags at a cost of 2 * 3 + 4 * 1 = $10. Therefore, the teacher must spend 7 + 10 = $17.
The answer: 17
Reverse engineering the question: An elementary school teacher is making Halloween goodie bags for her class. She wants the bags to be personalized, so she surveys her students asking whether they'd like a vampire-themed bag or a pumpkin-themed bag. Of her 25 students, 11 indicate they want the vampire-themed bag and 14 indicate they want the pumpkin-themed bag. The store the teacher shops at sells packs of 5 of each theme at a price of $3 per package, as well as individual bags of each theme at a price of $1 each. What is the least amount of money the teacher can spend on the bags if she buys every student the theme they requested?


Reasoning and answer: The samosas cost 3 * 2 = 6 dollars each. The pakoras cost 4 * 3 = 12 dollars each. The food came to 6 + 12 + 2 = 20 dollars. The tip was an additional 20 * .25 = 5 dollars. The total is 20 + 5 = 25.
The answer: 25
What was the question?
Question: At the Delicious Delhi restaurant, Hilary bought three samosas at $2 each and four orders of pakoras, at $3 each, and a mango lassi, for $2. She left a 25% tip. How much did the meal cost Hilary, with tax, in dollars?


If Phil had won 3 games more than did Charlie, and Phil won 12 games, then Charlie won 12 - 3 = 9 games. If Charlie had won 2 games fewer than Dana, and Charlie won 9 games, then Dana won 9 + 2 = 11 games. If Perry had won five more games than did Dana, and Dana won 11 games, then Perry won 11 + 5 = 16 games. Thus, Perry won 16 - 12 = 4 more games than did Phil.
The answer: 4
Reverse engineering the question: Perry, Dana, Charlie, and Phil played golf together every week. At the end of the season, Perry had won five more games than Dana, but Charlie had won 2 games fewer than Dana. Phil had won 3 games more than Charlie did. If Phil won a total of 12 games, how many more games did Perry win than did Phil?


Reasoning and answer: Twice 1.5 hours is 2 * 1.5 = 3 hours. Thus, on that day, it took Matthew 1 + 3 + 1 = 5 hours to make the cakes.
The answer: 5
What was the question?
Question: Matthew, the baker, arrives at work early every morning to make his famous caramel-apple coffee cakes for the day. It usually takes Matthew 1 hour to assemble ingredients, 1.5 hours to bake the cakes, and another 1 hour to decorate each cake with cinnamon sprinkles. One day, Matthew's oven failed to reach the correct temperature and it took twice as long for the cakes to bake as they usually take. On that day, how long did it take, in hours, for Matthew to make his famous caramel-apple coffee cakes?


First find the increase in rent by multiplying last year's rent by 30%: $1000 * .3 = $300. Then find the food cost increase by multiplying last year's costs by 50%: $200 * .5 = $100. Then find the new car insurance price by multiplying last year's price by 3: $100 * 3 = $300. Then subtract the cost of car insurance last year from this year's price to find the increase: $300 - $100 = $200. Now find how much Jessica's monthly expenses increased by adding the increases in each of the three costs: $300 + $100 + $200 = $600. Now multiply the increase per month by the number of months in a year to find the annual increase: $600 / month * 12 months / year = $7200 / year.
The answer: 7200
Reverse engineering the question: Last year Jessica paid $1000 for rent, $200 for food, and $100 for car insurance each month. This year her rent goes up by 30%, food costs increase by 50%, and the cost of her car insurance triples because she was at fault in an accident. How much more does Jessica pay for her expenses over the whole year compared to last year?


The four bags of Reese's cost $9 x 4 = $36. The three bags of Snickers cost $5 x 3 = $15. The five bags of Skittles cost $7 x 5 = $35. Therefore, the unicorn piñata and the treats cost $13 + $36 + $15 + $35 = $99.
The answer: 99
Reverse engineering the question:
It's Ava's birthday party. Her parents bought a unicorn piñata for $13 and filled it with all of her favorite treats. They bought 4 bags of Reese's for $9 per bag, 3 bags of Snickers for $5 per bag, and 5 bags of Skittles for $7 per bag. How much did the unicorn piñata and the treats cost altogether?
