The housewife has 3 / 3 - 2 / 3 = 1 / 3 of $150 left. This means she has $150 * (1 / 3) = $50 left.
The answer: 50
Reverse engineering the question: A housewife goes to the market. She spent 2/3 of her $150. How much does she have left?
Reasoning and answer: Bailey got 8 + 2 = 10 dog supplies. After adding the rawhide bones, she had 10 + 10 = 20 dog supplies. She needed to split the charges across 4 cards, so each charge had 20 * .25 = 5 items.
The answer: 5
What was the question?
Question: Bailey bought 8 dog treats and an additional 2 chew toys. She also got 10 more rawhide bones. Sadly, she forgot her money and had to split the charges equally across 4 credit cards. How many items were included in each charge?
Fred's barn started with 100 + 29 + 9 = 138 animals. Brian bought half of these, so there were 138 / 2 = 69 remaining. After Jeremy gifted Fred 37 goats, there were 69 + 37 = 106 animals in the barn. So, 106 / 2 = 53 of these animals are male.
The answer: 53
Reverse engineering the question: In Fred the Farmer's barn, there were 100 horses, 29 sheep, and 9 chickens. Brian bought half of the animals and sold them at the market. Jeremy then gifted Fred an additional 37 goats. If exactly half of the animals in the barn are male animals, how many male animals are there in the barn?
Reasoning and answer: First find the number of ounces Erin serves per minute: 10 ounces / bowl * 5 bowls / minute = 50 ounces / minute. Then find the number of ounces in the pot: 6 gallons * 128 ounces / gallon = 768 ounces. Then divide the total amount of soup by the amount of soup Erin serves per minute: 768 minutes / 50 ounces / minute = 15.36 minutes, which rounds down to 15 minutes.
The answer: 15
What was the question?
Question: Erin works in the school cafeteria serving soup. Each bowl of soup has 10 ounces, and Erin can serve 5 bowls per minute. If the pot of soup has 6 gallons of soup, how long will it take Erin to serve all the soup, rounded to the nearest minute? (There are 128 ounces to a gallon.)
The staff had eaten a total of 19 x 2 = 38 doughnuts. So, 50 - 38 = 12 doughnuts are left.
The answer: 12
Reverse engineering the question: During a staff meeting, 50 doughnuts were served. If each of the 19 staff ate 2 doughnuts, how many doughnuts are left?
The club has a female group which has twice as many members as the male group, so there are 2 + 1 = 3 groups in the club. There are 18 members in the club, which means there are 18 / 3 = 6 members per group. Since the number of female members consists of two groups, then there are 6 * 2 = 12 female members in the club.
The answer: 12
Reverse engineering the question:
In a glee club, there are two times as many female than male members. How many female members are there if there are 18 members in the club?
