A single watermelon would sell for $2 x 23 = $46. 60 watermelons would sell for $46 x 18 = $828.
The answer: 828
Reverse engineering the question: A watermelon weighs 23 pounds. If Farmer Kent sells his special watermelons for $2 a pound, how much money would he make for selling 18 watermelons of the same weight?
Reasoning and answer: He estimates the building on the left is 80 feet tall because 100 x .8 = 80. The combined height of the left and middle is 180 because 100 + 80 = 180. The building on the right he estimates as 160 feet because 180 - 20 = 160. He estimates the combined height as 340 feet because 80 + 100 + 160 = 340.
The answer: 340
What was the question?
Question: Quinten sees three buildings downtown and decides to estimate their heights. He knows from a book on local buildings that the one in the middle is 100 feet tall. The one on the left looks like it is 80% of the height of the middle one. The one on the right looks 20 feet shorter than if the building on the left and middle were stacked on top of each other. How tall does Quinten estimate their total height to be?
The third player eats 83 seeds because 53 + 30 = 83. They eat 214 in total because 78 + 53 + 83 = 214.
The answer: 214
Reverse engineering the question: At a softball game, three players are having a sunflower eating contest. The first player eats 78 seeds. The second eats 53 seeds. The third eats 30 more seeds than the second. How many do they eat in total?
Reasoning and answer: Mary needs 6 * 1 = 6 folders. Mary needs 6 * 3 = 18 pencils. Mary needs 18 / 6 = 3 erasers. Mary spends 6 * 6 = $36 on folders. Mary spends 18 * 2 = $36 on pencils. Mary spends 3 * 1 = $3 on erasers. Mary spends 36 + 36 + 3 = $75 on all the supplies except the paints. Mary spends 80 - 75 = $5 on the paint set.
The answer: 5
What was the question?
Question: Mary needs school supplies. She has 6 classes and needs 1 folder for each class. She also needs 3 pencils for each class. She decides that for every 6 pencils she should have 1 eraser. She also needs a set of paints for an art class. Folders cost $6, pencils cost $2, and erasers cost $1. If she spends $80, how much did the set of paints cost in dollars?
Peter is 10 years old because he has 10 birthday candles on his cake. Rupert is 3.5 times older than Peter so Rupert will have 3.5 * 10 = 35 candles on his cake.
The answer: 35
Reverse engineering the question: Peter and his dad Rupert shared the same birthday. To make it special, they each got their own birthday cake. Peter has 10 candles on his cake. Rupert is 3 and 1/2 times older than Peter. How many candles will be on Rupert's cake?
Since each package weighed 4 pounds, the first butcher delivered 10 * 4 = 40 pounds. The second butcher's delivery was 7 * 4 = 28 pounds. The first two butchers therefore delivered 40 + 28 = 68 pounds. Subtracting that weight from the total weight of ground beef gives 100 - 68 = 32 pounds. It therefore means the third butcher delivered 32 / 4 = 8 packages.
The answer: 8
Reverse engineering the question:
The owner of a Turkish restaurant wanted to prepare traditional dishes for an upcoming celebration. She ordered ground beef, in four-pound packages, from three different butchers. The following morning, the first butcher delivered 10 packages. A couple of hours later, 7 packages arrived from the second butcher. Finally, the third butcher's delivery arrived at dusk. If all the ground beef delivered by the three butchers weighed 100 pounds, how many packages did the third butcher deliver?
