First find Todd's contribution by doubling the boss's contribution: $15 * 2 = $30. Now subtract Todd and the boss's contributions to find out how much still needs to be paid: $100 - $30 - $15 = $55. Now divide the remaining cost by the number of employees to find the cost per employee: $55 / 5 employees = $11 / employee.
The answer: 11
Reverse engineering the question: Nick is asking all his co-workers to chip in for a birthday gift for Sandra that costs $100. The boss agrees to contribute $15, and Todd volunteers to contribute twice as much since he always has to one-up everyone. If the remaining 5 employees (counting Nick) each pay an equal amount, how much do they each pay?
Reasoning and answer: Lisa, Jessie, and Devin scored 311 - 188 = 123 points. 123 / 3 = 41. Jessie scored 41 points.
The answer: 41
What was the question?
Question: The Lady Eagles basketball team scored a total of 311 points in 5 games. Some players combined for 188 points. Lisa, Jessie, and Devin equally scored the rest. How many points did Jessie score?
Lara can bake 5 x 6 = 30 cookies in one tray. So, Lara is baking a total of 30 x 4 = 120 cookies.
The answer: 120
Reverse engineering the question: Lara is baking cookies using four baking trays. She places five rows of cookies on a baking tray where there are six cookies in one row. How many cookies is she baking?
Reasoning and answer: Mell's friends bought two bowls of ice cream, so that was a cost of 2 * 3 = $6. They all three bought two cups of coffee each, so they ordered 2 * 3 = 6 cups of coffee in total. The cost of the coffee was therefore 6 * 4 = $24. All her friends bought one piece of cake each, so the cost of it in total was 3 * 7 = $21. Mell and her friends spent in total 6 + 24 + 21 = $51 at the cafeteria.
The answer: 51
What was the question?
Question: Mell went to a cafeteria to spend some time with her friends. She ordered two cups of coffee and one piece of cake. Two of her friends ordered the same, but each of them also bought a bowl of ice cream. One cup of coffee is $4, one piece of cake is $7, and a bowl of ice cream is $3. How much money did Mell and her friends need to pay at the cafeteria?
He eats 2 boxes for 52 weeks so he eats 2 * 52 = 104 boxes. Each box costs $3.00 and he buys 104 boxes so he spends 3 * 104 = $312.00.
The answer: 312
Reverse engineering the question: Travis goes through 2 boxes of cereal a week. If each box costs $3.00 and he eats 2 boxes every week for an entire year, 52 weeks, how much does he spend on cereal?
Over the four hours, the tank loses 2 * 4 = 8 gallons of water. Hayden adds a total of 1 + 3 = 4 gallons of water. At the end of the four hours, there is 40 - 8 + 4 = 36 gallons of water left in the tank.
The answer: 36
Reverse engineering the question:
Hayden has a tank with a small hole in the bottom. The tank starts with 40 gallons of water. It loses 2 gallons of water per hour. Hayden does not add any water for the first two hours. He adds 1 gallon of water to the tank in hour three. He adds three gallons of water to the tank in the fourth hour. How much water is left in the tank at the end of the fourth hour?
