[Question]Lisa is a member of the photography club at school. Every weekend the club will go anywhere to take photos. Leslie took 10 photos of animals to share with the club. She also took 3 times as many photos of flowers as animals and took 10 fewer scenery than the flowers. If Lisa took 15 fewer photos last weekend, How many photos did she take then?
[Answer]Lisa took 10 x 3 = 30 photos of flowers. She took 30 - 10 = 20 photos of the scenery. So, Lisa took 10 + 30 + 20 = 60 photos this week. Therefore, Lisa took 60 - 15 = 45 photos last weekend. The answer is 45.
Q: Enid and Aaron are knitting clothes for their store. Aaron makes 10 scarves and 5 sweaters, and Enid makes 8 sweaters. If a scarf uses 3 balls of wool and a sweater uses 4 balls of wool, how many balls of wool did Enid and Aaron use in total?
A: Aaron used 10 scarves * 3 balls of wool = 30 balls of wool to make his scarves. He also used 5 sweaters * 4 balls of wool = 20 balls of wool to make his sweaters. Enid used 8 sweaters * 4 balls of wool = 32 balls of wool to make her sweaters. So in total, Aaron used 30 + 20 + 32 = 82 balls of wool. The answer is 82.
Question: Mark has the option of getting a $300 lens with a 20% discount or a $220 lens. How much money does he save by buying the cheaper lens?
Answer: The discount is worth 300 * .2 = $60. So the lens cost 300 - 60 = $240. That means he saves 240 - 220 = $20 by buying the cheaper lens. The answer is 20.
[Question]Jill likes to do small jobs online. She makes $10 a day for her first month working online, and double that per day in her second month. Her third month she makes the same amount per day as the previous month, but only works every other day. How much did she make over three months, assuming each month is 30 days long?
[Answer]Since there are 30 days in a month and Jill makes $10 a day her first month, she makes 30 * 10 = 300 dollars her first month. She makes twice the amount of the previous month's $300 in her second month, so she makes 2 * 300 = 600 dollars her second month. She makes the same amount per day the third month, but only works half the number of days, so she makes 600 / 2 = 300 dollars a month her third month. In total, she makes 300 + 300 + 600 = 1,200 dollars. The answer is 1200.
Q: Jill is going to resod her front yard. The plot of land in front of her house is 200 feet wide by 50 feet. Her house has a sidewalk that is 3 feet wide and 50 feet long. There are also four flower beds: two right in front of the house that are 4 feet deep by 25 feet long, one that is 10 feet by 12 feet, and a fourth that is 7 feet by 8 feet. How many square feet of sod will she need to cover her yard, minus the sidewalk and flower beds?
A: The area of the whole front yard is 200 feet by 50 feet, or 200 ft * 50 ft = 10,000 sq.ft. The sidewalk is 3 feet by 50 feet, or 3ft * 50ft = 150 sq.ft. Each of the flower beds right in front of the house is 4 feet by 25 feet, or 4 ft * 25 ft = 100 sq.ft. There are two, so that's 2 * 100 sq.ft. = 200 sq.ft. The third flower bed is 10 feet by 12 feet, or 10ft * 12ft = 120 sq.ft. The fourth flower bed is 7 feet by 8 feet, or 7ft * 8ft = 56 sq.ft. The total area of the sidewalk and flower beds is 150 sq.ft + 200 sq.ft + 120 sq.ft + 56 sq.ft = 526 sq. ft. So Jill will need a total of 10,000 sq.ft - 526 sq.ft = 9,474 sq.ft. of sod. The answer is 9474.
