20 tulip bulbs at $.50 each is 20 * .50 $10.00. She planted half that amount of iris' so 20 / 2 = 10 bulbs. 10 iris bulbs at $.50 each is 10 * .50 = $5.00. 30 daffodil bulbs at $.50 each is 30 * .50 = $15.00. She planted three times that amount of crocus bulbs to 30 * 3 = 90 bulbs. 90 crocus bulbs at $.50 = $45.00. All total, she earned 10 + 5 + 15 + 45 = $75.00.
The answer: 75
Reverse engineering the question: Jane's mother agreed to pay her $.50 for every flower bulb that Jane planted. Jane planted 20 tulip bulbs and half that amount of iris bulbs. She also planted 30 daffodil bulbs and three times that amount of crocus bulbs. How much money did Jane earn?


Reasoning and answer: The taco truck sold 3 + 2 * 10 = 3 + 20 = 23 soft tacos. It made 2 * 23 = $46 from soft tacos. It made 5 * 4 = $20 from hard shell tacos. Thus, the taco truck made 46 + 20 = $66 during the lunch rush.
The answer: 66
What was the question?
Question: A taco truck is selling soft tacos for $2 and hard shell tacos for $5 during the lunch rush. The first group of customers is a family that buys four hard shell tacos and three soft tacos. The rest of the customers in the lunch rush only buy two soft tacos each. There were ten customers after the family. How many dollars did the taco truck make during the lunch rush?


The number of students in elementary school is three less than four times the number in middle school: 4 * 50 students = 200 students. This means that there are 200 students - 3 students = 197 students in Elementary school. The total number of students in both levels is 197 students + 50 students = 247 students.
The answer: 247
Reverse engineering the question: There is three less than four times the number of students in Elementary School as there are in Middle School. If the number of students in Middle school is 50, calculate the total number of students in both levels.


Reasoning and answer: If Audrey was asleep for 10 hours last night and dreamed for 2 / 5 of the time, she dreamed for 2 / 5 * 10 = 4 hours. The total time Audrey slept without dreaming is 10 - 4 = 6 hours.
The answer: 6
What was the question?
Question: Audrey was asleep for 10 hours last night and dreamed for 2/5 of the time. How much of the night was she not dreaming?


Kim got 2 candy bars a week for 16 weeks so she got 2 * 16 = 32 candy bars. She would only eat 1 candy bar every 4 weeks so in 16 weeks she only ate 16 / 4 = 4 candy bars. She saved 32 candy bars and only ate 4 so she still has 32 - 4 = 28 candy bars.
The answer: 28
Reverse engineering the question: Kim's dad would buy her 2 candy bars a week. She would eat 1 candy bar every 4 weeks, saving the rest. After 16 weeks, how many candy bars did Kim have saved?


The bus traveled 55 + 10 = 65 miles going back to the starting point. So, the bus traveled a total of 55 + 65 = 120 miles. It took 120 x 2 = 240 minutes to travel. Since there are 60 minutes in 1 hour, then the bus traveled for 240 / 60 = 4 hours. Therefore, the entire tour took 4 + 2 = 6 hours.
The answer: 6
Reverse engineering the question:
Manex is a tour bus driver. He has to drive 55 miles to the destination and drive going back to the starting point on a different way that is 10 miles farther. If he can drive 1 mile for 2 minutes and stayed 2 hours at the destination, how long will it take the bus driver to do the entire tour in hours?
