Since Diana did 40 situps at a rate of 4 situps / minute, she did situps for 40 / 4 = 10 minutes. Hani had to do 3 + 4 = 7 situps per minute if Diana did 4 situps per minute. So over the 10 minutes Hani did 7 * 10 = 70 situps. Together, the total number of situps they did is 70 + 40 = 110.
The answer: 110
Reverse engineering the question: Hani said she would do 3 more situps per minute than Diana would. Diana then did 40 situps at a rate of 4 situps per minute. Calculate the total number of situps they did together.
Reasoning and answer: Shelly catches 2 less than five swordfish each time they go fishing, for a total of 5 - 2 = 3 fish per trip. Sam catches one less swordfish than does Shelly on each trip, or a total of 3 - 1 = 2 swordfish per trip. Together, they catch a total of 3 + 2 = 5 swordfish on each trip. If Sam and Shelly go fishing 5 times, they catch a total of 5 * 5 = 25 swordfish.
The answer: 25

Question: Shelly and Sam love to go deep sea fishing for swordfish. Each time they go deep sea fishing, Shelly catches 2 less than five swordfish, and Sam catches one less swordfish than Shelly. If Sam and Shelly go fishing 5 times, how many swordfish do they catch in total?
If half of the people in Nantucket are going to the planned meeting, then there are 1 / 2 * 300 = 150 people going to the meeting. If the number of males going to the meeting is twice the number of females, we'll assume the number of females is x and the number of males is 2x. We know that x + 2x = 150. Adding like terms produces 3x = 150. After dividing both sides by 3, we have x = 150 / 3 = 50. The number of females attending the meeting is x = 50.
The answer: 50
Reverse engineering the question: Half of all the people in Nantucket will attend a planned meeting for a bowl game. There are 300 people in Nantucket, and the number of males going to the meeting is twice the number of females. How many females are going to the meeting?
Reasoning and answer: For the first week, Cody will log a total of 7 * 1,000 = 7,000 steps. For the second week, Cody will log a total of 7 * 2,000 = 14,000 steps. For the third week, Cody will log a total of 7 * 3,000 = 21,000 steps. For the fourth week, Cody will log a total of 7 * 4,000 = 28,000 steps. For the month, Cody will log a total of 7,000 + 14,000 + 21,000 + 28,000 = 70,000 steps. This means, Cody will be 100,000 - 70,000 = 30,000 steps short of his goal.
The answer: 30000

Question: Cody has an insurance plan that will give him a discount if he logs a total of 100,000 steps. For the first week, he logs 1,000 steps a day. He increases his daily number of steps by 1,000 every week. After 4 weeks how far away from his step goal will he be?
The rival team won twice as many as the home team who won 3 matches so they won 2 * 3 = 6 matches. They both drew 4 matches each for a total of 2 * 4 = 8 matches. The total number of matches played is 3 + 6 + 8 = 17 matches.
The answer: 17
Reverse engineering the question: A rival football team has won twice as many matches as the home team they will be playing did. If records show that the home team has won three matches, and each team drew four matches and lost none, how many matches have both teams played in total?
First find how many of the peaches are fresh, which is 250 peaches * 60% = 150 peaches. Then, subtract the number Brenda throws away after the fresh count, which is 150 peaches - 15 peaches = 135 peaches.
The answer: 135
Reverse engineering the question:
Brenda picks 250 peaches. When she sorts through them, only 60% are fresh, and Brenda has to throw 15 away for being too small. How many peaches does Brenda have left?
