Reasoning and answer: First Jamie wants to figure out how many calories his father needs to lose from 5 pounds x 3500 calories each = 17,500 calories to burn off. Then Jamie needs to figure out how many calories his father will burn per day if he burns 2500 calories - eating 2000 calories = burning 500 calories a day. If Jamie's father wants to burn off 17,500 calories total at 500 calories a day, 17,500 / 500 = 35 days to burn off 5 pounds.
The answer: 35

Question: Jamie's father gained 5 pounds over the holidays that he wants to lose so his pants will not be as snug. He asks Jamie to help him keep track of his calories. Jamie's father burns 2,500 calories of fat a day by doing light exercise. There are 3,500 calories in a pound of body fat. How many days will it take for Jamie's father to burn off 5 pounds if he does light exercise and sticks to eating 2000 calories a day?


Paul doubles the amount that he ate on the second day, so eats 2 x 2 = 4 sandwiches. For the third day, he doubles the number of sandwiches he ate on the second day, so eats 2 x 2 x 2 = 8 sandwiches. To get the total amount of sandwiches he ate over three days it's necessary to add up the amount he ate each day: 2 + 4 + 8 = 14 sandwiches. Since he eats 14 sandwiches every 3 days, then in 6 days he would eat 14 x 2 = 28 sandwiches in total.
The answer: 28
Reverse engineering the question: Paul eats a lot when he studies. He loves sandwiches and eats them at the same rate every three days. He eats 2 sandwiches the first day, then doubles that number of sandwiches for the second day. On the third day, he doubles the number of sandwiches he ate on the second day. How many sandwiches would Paul eat if he studied 6 days in a row?


Reasoning and answer: Melony makes $21 * 4 = $84 of profit for two pairs of sandals. Melony makes $84 / 2 pairs = $42 of profit per pair of shoes. Melony makes $21 / 3 shirts = $7 of profit per shirt. For seven shirts, Melony will make 7 shirts * $7 = $49 of profit. For three pairs of sandals, Melony will make 3 pairs * $42 / pair = $126 of profit. Melony will make a total of $49 + $126 = $175 of profit.
The answer: 175

Question: Melony makes $21 of profit every time she sells 3 shirts and four times as much profit when she sells two pairs of sandals. How much profit will she make if she sells 7 shirts and 3 pairs of sandals?


Each dog consumes 1.5 x 3 = 4.5 cups of food a day. In pounds, this is equal to 4.5 / 2.25 = 2. So both consume 2 x 2 = 4 pounds of food.
The answer: 4
Reverse engineering the question: Tracy feeds each of her two dogs 1.5 cups of food per meal. She feeds her dogs thrice a day. How many pounds of food do her two dogs consume if 1 pound is equal to 2.25 cups?


Reasoning and answer: 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
What was the question?
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?


Reasoning and answer: If you answer every question correctly in the test, the total possible marks are 50 * 2 = 100 marks. If Jose got five questions wrong, he lost 5 * 2 = 10 marks because each question has two marks. Therefore, Jose scored 100 - 10 = 90 marks on the test. Meghan scored 20 marks less than that which Jose got, a total of 90 - 20 = 70 marks. The total marks that Jose and Meghan scored in the test are 70 + 90 = 160. Alisson scored 90 - 40 = 50 marks in the examination, 40 marks less than that which Jose scored on the test. The total number of marks that the three scored in the test is 160 + 50 = 210.
The answer: 210
