Reasoning and answer: The amount that the couple would cover for the hospital bill is $128 / 2 = $64. The couple's total expenses (salary and hospital bill) is $160 + $64 = $224. So each of them should give $224 / 2 = $112 in total. Since the husband paid the entire half of the hospital bill already ($64), he still needs to pay $112 - $64 = $48.
The answer: 48

Question: A couple agreed to split their expenses equally, including the salary of their house help. While doing her job, the house help had an accident; thus, she underwent a medical procedure which cost her $128. The couple decided to pay half of the medical expenses and the other half will be deducted from her $160 salary. If the husband paid for the entire half of the hospital bill, how much does he still need to pay so that they split the expenses for the house help equally?
When Jonah ran for 2 hours, burning 30 calories every hour, he burnt a total of 2 * 30 = 60 calories. If he had run for five hours, losing 30 calories every hour, Jonah would have burnt 5 * 30 = 150 calories. The difference in the number of calories Jonah would have burnt if he ran for five hours instead of 2 hours is 150 - 60 = 90 calories.
The answer: 90
Reverse engineering the question: Running for 2 hours, Jonah burnt 30 calories every hour. How many more calories would he have lost if he would have run for five hours?
Reasoning and answer: First find the number of seeds that land in water: 300 seeds * 1 / 3 = 100 seeds. Then find the number of seeds that are eaten: 300 seeds * 1 / 6 = 50 seeds. Subtract the number of seeds that are destroyed to find the number that sprout: 300 seeds - 100 seeds - 50 seeds = 150 seeds. Then divide that number by 2 to find the number of sprouts that survive: 150 seeds / 2 = 75 seeds.
The answer: 75

Question: Each dandelion produces 300 seeds. 1/3rd of the seeds land in water and die. 1/6 of the starting number are eaten by insects. Half the remainder sprout and are immediately eaten. How many dandelions survive long enough to flower?
There were 10 eggs but 5 of them were used so, there are 10 - 5 = 5 eggs. Then the two chickens laid 2 * 3 = 6 eggs in total. Thus, the family has 5 + 6 = 11 eggs now.
The answer: 11
Reverse engineering the question: A family had 10 eggs, but the mother used 5 of them to make an omelet. Then, 2 chickens laid 3 eggs each. How many eggs does the family have now?
Reasoning and answer: Jameson has 5 x 2 = 10 medals for swimming. He has a total of 5 + 10 = 15 medals for track and swimming. Thus, he has 20 - 15 = 5 medals for badminton.
The answer: 5
What was the question?
Question: Jameson has 20 medals. Five of the medals are for the track. He has two times as many swimming medals as track medals. The rest of the medals are for badminton. How many badminton medals does he have?
Reasoning and answer: First, we find out how much in sales the stand makes each hour by multiplying the number of hot dogs sold by the sales price, finding that 2 * 10 = 20 dollars in sales each hour. Then we divide the sales goal for the day by the sales per hour, finding that the stand needs to be open for 200 / 20 = 10 hours to hit its sales goal.
The answer: 10

Question:
A hot dog stand sells 10 hot dogs every hour, each one selling for $2. How many hours does the stand need to run to make $200 in sales?
