[Question]Ann is cutting fabric to make curtains. She cuts a 4 foot by 6 foot rectangle for the living room, and a 2 foot by 4 foot rectangle for the bedroom. If the bolt of fabric is 16 feet by 12 feet, how much fabric is left in square feet?
[Answer]First figure out how many square feet the original bolt of fabric was: 16 feet * 12 feet = 192 square feet. Then figure out how much fabric Ann took for the living room curtains: 4 feet * 6 feet = 24 square feet. Then figure out how much fabric Ann took for the bathroom curtains: 2 feet * 4 feet = 8 square feet. Finally, subtract the square footage of both sets of curtains from the total square footage: 192 - 24 - 8 = 160 square feet. The answer is 160.

[Question]After 100 new people move into a town, 400 of the original population move out. Every year afterward, the town’s population is halved. After 4 years, the population is 60 people. Before the new people moved in, how many people lived in the town?
[Answer]If the population is halving then at the end of the third year, the population must have been 60 people in the fourth year * 2 = 120 people. In the second year, the population was 120 people in the third year * 2 = 240 people. And in the first year, the population was 240 people in the third year * 2 = 480 people. Additional people moved out in the first year, so accounting for these shows the population was 480 people + 400 people who moved out = 880 people. Then removing the new people shows there were originally 880 people – 100 new people = 780 people. The answer is 780.

[Question]Kaiden and Adriel were to pick a certain number of apples from their farm. After picking 400 apples each, they realized they still had to pick some more, so each picked 3/4 times as many as they had picked earlier. When they checked the pickup truck that was carrying the apples, they found out they still needed to pick 600 apples each to reach the target number. How many apples were they targeting to pick?
[Answer]When they picked 400 apples each in the first round, they picked a total of 2 * 400 = 800 apples. They picked 3 / 4 * 400 = 300 apples each in the second round. The total number of apples they picked in the second round is 2 * 300 = 600. The total number of apples they'd picked so far is 800 + 600 = 1400. When they checked the pickup truck that was carrying the apples, they found out they still needed to pick 600 apples each to reach the target number, a total of 2 * 600 = 1200. The target number of apples they had to pick is 1200 + 1400 = 2600. The answer is 2600.

[Question]At peak season, 6 packs of tuna fish are sold per hour, while in a low season 4 tuna packs are sold per hour. If each tuna pack is sold at $60, How much more money is made in a day during a high season than a low season if the fish are sold for 15 hours?
[Answer]
6 packs of tuna fish are sold per hour. If the sales are made for 15 hours, the total number of packs sold is 4 = 6 * 15 = 90 packs. At $60 per pack, during a high season, the total sales in 15 hours are 90 * $60 = $5400. 4 packs of tuna fish are sold per hour. If the sales are made for 15 hours, the total number of packs sold is 4 * 15 = 60 packs. At $60 per pack, during a low season, the total sales in 15 hours are 60 * $60 = $3600. The amount of money that is made after 15 hours during a high season than a low season is $5400 - $3600 = $1800. The answer is 1800.
