Betty paid 6 x $2.5 = $15 for the slippers. She paid 4 x $1.25 = $5 for the lipsticks. She paid 8 x $3 = $24 for the hair color. Therefore, Betty paid $15 + $5 + $24 = $44 in total.
The answer: 44
Reverse engineering the question: Betty ordered 18 items in an online shop via cash on delivery. She ordered 6 pieces of slippers that cost $2.5 each, 4 pieces of lipstick for $1.25 each, and 8 pieces of hair color for $3 each. How much did Betty pay in total when it was delivered?
Reasoning and answer: The 20 big toenails take up as much space as 40 regular toenails because 20 x 2 = 40. She has filled up 80 toenails worth because 40 + 40 = 80. She can fit 20 regular toenails in the jar because 100 - 80 = 20.
The answer: 20
What was the question?
Question: Hilary is collecting her toenails in a jar to gross out her sister. She can fit 100 toenails in the jar, unless they are from her two big toes, which are twice as big as the rest. She has already filled it with 20 big toenails and 40 regular toenails. How many regular toenails can she fit into the remainder of the jar?
The cost of the pots is 3 * $20 = $60. The cost of 4 pans is $100 - $60 = $40. Since each pan is the same price, the cost of 1 pan is $40 / 4 = $10. The cost of 2 pans is $10 + $10 = $20.
The answer: 20
Reverse engineering the question: Katerina purchases 3 pots and 4 pans at the home goods store. Each pot costs $20. The total cost of Katerina's items is $100. If each pan is the same price, what is the cost of 2 pans?
Reasoning and answer: Renaldo = 15 km. Ernesto = (1 / 3) * 15 + 7 = 12 km. Total = 15 + 12 = 27 km. Renaldo and Ernesto drove a total of 27 kilometers.
The answer: 27
What was the question?
Question: Renaldo drove 15 kilometers. Ernesto drove 7 kilometers more than one-third of Renaldo's distance. How many kilometers did the 2 men drive in total?
Carmela's four cousins have a total of $2 x 4 = $8. The total money they all have is $7 + $8 = $15. There will be 1 (Carmela) + 4 (cousins) = 5 people who will be sharing equally the money. So each of them should get $15 / 5 = $3. Hence, Carmela has to give a total of $7 - $3 = $4 to her 4 cousins. Therefore, each of her cousins will get $4 / 4 = $1.
The answer: 1
Reverse engineering the question: Carmela has $7 and each of her four cousins has $2. How much will Carmela have to give to each of her cousins so that she and her cousins will have the same amount of money?
She has 144 square inches of dough because 12 times 12 equals 144. Each biscuit uses 9 square inches of dough because 3 times 3 equals 9. She can make 16 biscuits because 144 divided by 9 equals 16.
The answer: 16
Reverse engineering the question:
Unique is making biscuits. She has a sheet of dough that is 12 inches by 12 inches. She makes square biscuits and each biscuit is 3 inches by 3 inches. How many biscuits can she make with this dough?
