Reasoning and answer: Angela has 6 + 3 * 20 = 66 plates. Angela has 1 / 2 * 66 = 33 cutlery. Sharon wants to buy 1 / 2 * 20 = 10 pots. Sharon wants to buy 3 * 66 - 20 = 178 plates. Sharon wants to buy 2 * 33 = 66 cutlery. Sharon wants to buy a total of 10 + 178 + 66 = 254 kitchen supplies.
The answer: 254

Question: Sharon wants to get kitchen supplies. She admired Angela's kitchen supplies which consist of 20 pots, 6 more than three times as many plates as the pots, and half as many cutlery as the plates. Sharon wants to buy half as many pots as Angela, 20 less than three times as many plates as Angela, and twice as much cutlery as Angela. What is the total number of kitchen supplies Sharon wants to buy?


Sarah and the final neighbor took the wrong amount, which means that 15 neighbors – 1 Sarah – 1 final neighbor = 13 neighbors took 10 cookies each. This is a total of 13 neighbors * 10 cookies = 130 cookies taken by the first 13 neighbors. There were only 8 cookies left, so that means the first 13 neighbors and Sarah took a total of 150 – 8 = 142 cookies. So Sarah must have taken 142 – 130 = 12 cookies.
The answer: 12
Reverse engineering the question: Edna made cookies for all of her neighbors and left the cookies outside for them to take. She made 150 cookies so her 15 neighbors could get 10 cookies each. However, the neighbor who arrived last told Edna there were only 8 cookies left. Edna thinks it was Sarah who took too many cookies. If all the other neighbors took the correct amount of cookies, how many cookies did Sarah take?

He will need 300 ounces of water because 100 x 3 = 300. He will need 6 bottles because 300 / 50 = 6. This will cost $15 because 6 x 2.5 = 15. He has $20 because 2 x 10 = 20. He will get $5 in change because 20 - 15 = 5.
The answer: 5

Reasoning and answer: After one year, Sam had $10,000 * 1.2 = $12,000. After two years, he had $12,000 * 1.2 = $14,400. After the third year, he had $14,400 * 1.2 = $17,280. He then invested more money until he had 3 * $17,280 = $51,840. The first year after that, he had $51,840 * 1.15 = $59,616.
The answer: 59616

Reasoning and answer: On 80 games, Daniel spend 80 games * $12 / game = $960. The rest of the collection is 346 games - 80 games = 266 games. 50% of these games means 50 / 100 * 266 games = 133 games. Daniel bought them for $7 each, so he had to spend 133 games * $7 / game = $931 on them. The other 133 games were bought for $3 each, so they've cost him 133 games * $3 / game = $399. On all games in total Daniel spent $960 + $931 + $399 = $2290.
The answer: 2290
