First we need to know what half of Bills toys are, 60 toys / 2 = 30 toys. Hash has 9 toys + 30 toys = 39 toys. Together the boys have 60 toys + 39 toys = 99 toys.
The answer: 99
Reverse engineering the question: Hash has nine more than half as many toys as Bill has. If Bill has 60 toys, how many total toys do the boys have?
Reasoning and answer: The total cost for roses is 20 * 5 = $100. Nadia bought 3 / 4 * 20 = 15 lilies. Each lily costs 5 * 2 = $10. She used 10 * 15 = $150 in total to buy lilies. To buy all the flowers, Nadia used 150 + 100 = $250.
The answer: 250
What was the question?
Question: Nadia was sent to the flower shop to buy 20 roses and 3/4 times as many Lillies as roses. If roses cost $5 each and lilies cost twice as much each, calculate the total amount of money Nadia used to buy the flowers.
The total number of pages is 180 + 100 = 280 pages. The number of pages Yasna needs to read every day for two weeks is 280 / 14 = 20 pages.
The answer: 20
Reverse engineering the question: Yasna has two books. One book is 180 pages long, and the other book is 100 pages long. If Yasna wants to finish both of the books in two weeks, how many pages will Yasna need to read every day, if she reads an equal number of pages each day?
Reasoning and answer: Armand = (1 / 3) * 12 = 4 hours. Ella = 2 * 12 = 24 hours. Total hours = 12 + 4 + 24 = 40 hours. They worked a total of 40 hours.
The answer: 40
What was the question?
Question: Amber worked for 12 hours last weekend. Armand worked one-third as long and Ella worked twice as long. How many hours did the 3 people work in total?
The amoeba will divide into 1 * 2 = 2 amoebae after 2 days. The amoeba will divide into 2 * 2 = 4 amoebae after 4 days. The amoeba will divide into 4 * 2 = 8 amoebae after 6 days. The amoeba will divide into 8 * 2 = 16 amoebae after 8 days.
The answer: 8
Reverse engineering the question: An amoeba reproduces by fission, splitting itself into two separate amoebae. An amoeba reproduces every two days. How many days will it take one amoeba to divide into 16 amoebae?
The price of the washing machine is $4275 - $1490 = $2785. The total price of the purchases is $4275 + $2785 = $7060.
The answer: 7060
Reverse engineering the question:
Your mom bought a refrigerator and a washing machine. Note that the price of the refrigerator is $4275 and the price of the washing machine is $1490 less than the price of the refrigerator. Calculate the total price of the purchases in dollars.
