Question: Happy Cattle Ranch is home to 200 cows. Every year, the mother cows have enough calves that the number of cows the rancher owns rises by half the number of cows living on the ranch.

The double cone has 2 * 1 = 2 scoops of ice cream. The banana split has three times as many scoops of ice cream as the single cone, so it has 3 * 1 = 3 scoops of ice cream. The waffle bowl has 1 more scoop of ice cream than the banana split, so it has 3 + 1 = 4 scoops of ice cream. The ice cream man served a total of 1 + 2 + 3 + 4 = 10 scoops of ice cream.
The answer: 10
Reverse engineering the question: Camille goes to the Ice Cream Palace with her husband and two children. Each one orders a different ice cream. Camille orders a banana split, her husband orders a waffle bowl, her daughter orders a single cone, and her son orders a double cone. The cone has 1 scoop of ice cream, the banana split has 3 times as many scoops of ice cream as the cone and the waffle bowl has 1 more scoop than the banana split. How many scoops of ice cream did the ice cream man serve?


Reasoning and answer: Mr. Deane will spend $1.4 / liter x 10 liters = $14 for the 10 liters of gas today. The price of the gas per liter on Friday will be $1.4 / liter - $0.4 / liter = $1 / liter. So, he will spend $1 / liter x 25 liters = $25 for the 25 liters of gas on Friday. Thus, Mr. Deane will spend a total of $14 + $25 = $39 for the 35 liters of gas.
The answer: 39

Question: The news announced a $0.4 oil price rollback this Friday. Mr. Deane decided to only fill his gas tank with 10 liters of gas today and then another 25 liters on Friday. If the cost per liter of gas is $1.4 today, how much will Mr. Deane spend for his 35 liters of gas?


Kaiden collects 158 cans his first week and 259 cans during the second week. 158 + 259 = 417 cans of soup. Kaiden wants to collect a total of 500 cans, so he still needs 500 - 417 = 83 cans of soup.
The answer: 83
Reverse engineering the question: Kaiden is collecting cans of soup for the local soup kitchen. He collects 158 cans during his first week and 259 during the second week. If his goal is to collect 500 cans how many more cans of soup does he need to collect?

Reasoning and answer: It's a 100 - foot fence, and Ben whitewashed 10 feet, so there are 100 - 10 = 90 feet left after Ben is done. Billy whitewashed a fifth of that, or 90 / 5 = 18 feet. There is now 90 - 18 = 72 feet of fence left. Johnny whitewashes a third of that, or 72 / 3 = 24 feet. That leaves 72 - 24 = 48 feet of fence left to be whitewashed.
The answer: 48
