Question: Irene shares half of a small apple with her dog every day. A small apple weighs about 1/4 of a pound. She can currently buy apples for $2.00 a pound. How much will she spend so that she and her dog have enough apples to last for 2 weeks?
Answer: There are 7 days in a week and she needs apples for 2 weeks so that's 7 * 2 = 14 days. She shares an apple with her dog every day so for 14 days so she needs 1 * 14 = 14 apples. Each apple weighs 1 / 4 of a pound and she needs 14 apples so that's .25 * 14 = 3.5 pounds of apples. She needs 3.5 pounds of apples and they are on sale for $2.00 a pound so she will spend 3.5 * 2 = $7.00 for apples. The answer is 7.
[Question]Jenna is making a costume for her role in Oliver Twist. She needs to make an overskirt and two petticoats. Each skirt uses a rectangle of material that measures 12 feet by 4 feet. She also needs to make a bodice that uses 2 square feet of material for the shirt and 5 square feet of fabric for each of the sleeves. If the material she uses costs $3 per square foot, how much does she spend on the material in total?
[Answer]First find the amount of material needed for one skirt: 12 feet * 4 feet = 48 square feet. Then multiply that number by the number of skirts to find the total material used on the skirts: 48 square feet / skirt * 3 skirts = 144 square feet. Then find the total amount of material she uses for the sleeves: 5 square feet / sleeve * 2 sleeves = 10 square feet. Then add the amount of material she uses for each part of the dress to find the total amount of material: 10 square feet + 144 square feet + 2 square feet = 156 square feet. Then multiply the total amount of material by the cost per square foot to find the total cost: 156 square feet * $3 / square foot = $468. The answer is 468.
Q: There are 10 books on the table. Two-fifths of them are reading books and three-tenths of them are math books. There is one fewer science book than math books and the rest are history books. How many history books are there?
A: Out of the 10 books, 10 x 2 / 5 = 4 are reading books. While 10 x 3 / 10 = 3 are math books. There are 3 - 1 = 2 science books. So, the total number of reading, math, and science books is 4 + 3 + 2 = 9. Thus, there is only 10 - 9 = 1 history book. The answer is 1.
Question: Five shirts together cost $85. Of the 5 shirts, there are 3 shirts that cost $15 each. If the remaining shirts are each equal in value, what is the cost, in dollars, of one of the remaining shirts?
Answer: The first 3 shirts cost 15 * 3 = 45 dollars in total. There are 5 - 3 = 2 shirts remaining. The remaining 2 shirts cost 85 - 45 = 40 dollars in total. One of the remaining shirts costs 40 / 2 = 20 dollars. The answer is 20.
[Question]If farmer Steven can use his tractor to plow up to 10 acres of farmland per day, or use the same tractor to mow up to 12 acres of grassland per day, how long would it take him to plow his 55 acres of farmland and mow his 30 acres of grassland?
[Answer]At a rate of 10 acres per day, he can plow his 55 acres of farmland in 55 / 10 = 5.5 days. At a rate of 12 acres per day, he can mow his 30 acres of grassland in 30 / 12 = 2.5 days. Altogether, it would take him 5.5 + 2.5 = 8 days to completely mow and plow his land. The answer is 8.
[Question]Jake is retrieving the notes on a communal board, putting all of the red notes in the complaints bin and all of the blue notes in the compliments bin. The red notes were in 5 rows with 6 notes in each row. There are 2 blue notes under each of the red notes, as well as another 10 blue notes scattered at the bottom of the board. How many notes in total are put into the complaints and compliments bins?
[Answer]
There are a total of 5 rows of red notes * 6 notes per row = 30 red notes on the board. There are 2 blue notes per red notes * 30 red notes = 60 blue notes under the red notes. With the other blue notes at the bottom of the board, there are a total of 60 + 10 = 70 blue notes. So in total, there are 30 red notes + 70 blue notes = 100 notes in total. The answer is 100.
