Ted planted 2 x 50 = 100 tomato seeds. So, Mike and Ted planted 50 + 100 = 150 tomato seeds in the morning. In the afternoon, Ted planted 60 - 20 = 40 seeds. Thus, Mike and Ted planted 60 + 40 = 100 tomato seeds in the afternoon. Therefore, they planted 150 + 100 = 250 tomato seed altogether.
The answer: 250
Reverse engineering the question: Mike and Ted planted tomatoes. In the morning, Mike planted 50 tomato seeds while Ted planted twice as much as Mike. In the afternoon, Mike planted 60 tomato seeds while Ted planted 20 fewer tomato seeds than Mike. How many tomato seeds did they plant altogether?


Reasoning and answer: He is driving 40 MPH because 120 / 3 = 40. It will take him 5 hours because 200 / 40 = 5.
The answer: 5
What was the question?
Question: Tony is driving his car between his town and a friend's down. The towns are 120 miles apart and he gets there in 3 hours. The next day, he is driving to see another friend who lives 200 miles away from his friend. If he drives at the same speed, how long will the drive take?


The total number of green and red plates is 28 + 21 = 49. Xavier should buy 84 − 49 = 35 more plates.
The answer: 35
Reverse engineering the question: Xavier needs 84 paper plates for a housewarming party. He already has 21 green plates and 28 red plates. How many more plates should Xavier buy?

The answer: 4
What was the question?
Question: There are 14 kindergartners and 24 first graders and some second graders in Ms. Watson's class. Overall Ms. Watson has 42 students. How many second graders are in Ms. Watson’s class?


If one meatball is made from 1 / 8 pound of hamburger meat, then 4 pounds of hamburger meat will make 4 / (1 / 8) = 4 * 8 = 32 meatballs. 32 meatballs divided amongst 8 family members is 32 / 8 = 4 meatballs per family member.
The answer: 4
Reverse engineering the question: Antonio is preparing a meal of spaghetti and meatballs for his family. His recipe for meatballs calls for 1/8 of a pound of hamburger per meatball. Antonio has 8 family members, including himself. If he uses 4 pounds of hamburger to make meatballs, and each member of the family eats an equal number of meatballs, how many meatballs will Antonio eat?
