A leap year is one day shorter than a regular year, so it is 365 – 1 = 364 days. Brittany washes her hair every other day, so she will wash it 364 / 2 = 182 times in a leap year. A bottle of shampoo lasts her 14 / 1 / 4 = 14 * 4 = 56 washes. If she buys 3 bottles, she will only have enough for 56 * 3 = 168 washes. If she buys 4 bottles, she will have enough for 56 * 4 = 224 washes. Since 168 < 182 and 224 > 182, Brittany needs 4 bottles of shampoo to get her through a leap year.
The answer: 4
Reverse engineering the question: Brittany uses 1/4 ounce of shampoo to wash her hair every other day. She buys shampoo in 14-ounce bottles. How many bottles does she need to get her through a leap year?


Reasoning and answer: 5 packs of gum contain 5 * 3 = 15 sticks of gum. If each brown box contains 4 cartons, 8 brown boxes contain 8 * 4 = 32 cartons. So, 8 brown boxes contain 32 * 15 = 480 sticks of gum.
The answer: 480
What was the question?
Question: A warehouse store sells cartons of gum. Each carton contains 5 packs of gum, and there are 3 sticks of gum in each pack. Each brown box contains 4 cartons of gum. How many sticks of gum are there in 8 brown boxes?


Between 2:30 pm and 5:00 pm, there are 2.5 hours. There are 60 minutes in an hour, so 2.5 hours x 60 = 150 minutes. Her family was in the bathroom 45 + 30 + 20 = 95 minutes. Mrs. Parker has 150 minutes – 95 minutes = 55 minutes in the bathroom.
The answer: 55
Reverse engineering the question: The Parker family needs to leave the house by 5 pm for a dinner party. Mrs. Parker was waiting to get into the bathroom at 2:30 pm. Her oldest daughter used the bathroom for 45 minutes and her youngest daughter used the bathroom for another 30 minutes. Then her husband used it for 20 minutes. How much time will Mrs. Parker have to use the bathroom to leave on time?


Reasoning and answer: Twice the age of Shara is 10 x 2 = 20. So, Jaymee is 20 + 2 = 22 years old.
The answer: 22
What was the question?
Question: Jaymee is 2 years older than twice the age of Shara. If Shara is 10 years old, how old is Jaymee?


Amanda has 7 - 3 = 4 candy bars. Amandy gives her sister 4 x 3 = 12 candy bars. She has 30 - 12 = 18 candy bars remaining. In total she keeps 18 + 4 = 22 candy bars.
The answer: 22
Reverse engineering the question: Amanda had 7 candy bars. She gave 3 to her sister. The next day, Amanda won some prize money and bought another 30 candy bars. She gave her sister 4 times as many candy bars as she did the first time. How many candy bars did Amanda keep for herself altogether?


Kylie makes 10 + 2 = 12 beaded necklaces. The number of beads used for the necklaces is 12 * 20 = 240 beads. The number of beads used for the bracelets is 5 * 10 = 50 beads. The number of beads used for the earrings is 7 * 5 = 35 beads. The total number of beads used is 240 + 50 + 35 = 325 beads.
The answer: 325
Reverse engineering the question:
Kylie makes 10 beaded necklaces on Monday and 2 beaded necklaces on Tuesday. Then Kylie makes 5 beaded bracelets and 7 beaded earrings on Wednesday. 20 beads are needed to make one beaded necklace. 10 beads are needed to make one beaded bracelet. 5 beads are needed to make one beaded earring. How many beads does Kylie use in total to make her jewelry?
