[Question]Carly is making burgers for a neighborhood BBQ. Each burger needs to be cooked for 4 minutes on each side. Carly can fit 5 burgers on the grill at once. If half her 30 guests want 2 burgers and the other half each want 1, how long will it take Carly to cook all the burgers?
[Answer]First find half the number of guests at Carly's party: 30 guests / 2 = 15 guests. Then multiply that number by 2 for the number of burgers half the guests want: 15 guests * 2 burgers / guest = 30 burgers. Then add the 15 burgers for the 15 guests who only want 1 to find the total number of burgers: 30 burgers + 15 burgers = 45 burgers. Then divide the total number of burgers by the number of burgers Carly can cook at once to find the number of batches she cooks: 45 burgers / 5 burgers / batch = 9 batches. Then multiply the number of sides per burger by the cooking time per side to find each burger's total cook time: 4 minutes / side * 2 sides = 8 minutes. Finally, multiply each batch's cook time by the number of batches to find the total cook time: 8 minutes / batch * 9 batches = 72 minutes. The answer is 72.
Q: Candice read 3 times as many books as Amanda in their school's Book Tournament. Kara read half the number of books that Amanda read, and Patricia read 7 times the number of books that Kara read. If Candice read 18 books, how many books did Patricia read?
A: Amanda read 18 / 3 = 6 books. Kara read 6 / 2 = 3 books. Patricia read 7 x 3 = 21 books. The answer is 21.
Question: Milly and Floretta are having a water balloon fight in their garden. They use 3 packs of their own water balloons and also use 2 packs of a neighbor’s water balloons. Each pack of water balloons contains 6 balloons. Milly and Floretta fill all of the balloons then split them evenly, but Milly takes an extra 7 balloons when Floretta isn't looking. How many water balloons is Floretta left with?
Answer: Milly and Floretta have a total of 3 packs of their own water balloons + 2 packs of the neighbor’s water balloons = 5 packs of water balloons. So there is a total of 5 packs of water balloons * 6 balloons per pack of water balloons = 30 water balloons available. As they split them evenly, they each have 30 water balloons / 2 = 15 water balloons. After Milly steals some balloons, Floretta is left with 15 – 7 = 8 water balloons. The answer is 8.
[Question]Bill is trying to decide whether to make blueberry muffins or raspberry muffins. Blueberries cost $5.00 per 6 ounce carton and raspberries cost $3.00 per 8 ounce carton. If Bill is going to make 4 batches of muffins, and each batch takes 12 ounces of fruit, how much money would he save by using raspberries instead of blueberries?
[Answer]First find how many ounces of fruit Bill will need total: 12 ounces / batch * 4 batches = 48 ounces. Then find how many cartons of blueberries Bill would need: 48 ounces / 6 ounces / carton = 8 cartons. Then multiply that number by the cost per carton to find the total cost of the blueberries: 8 cartons * $5 / carton = $40. Then find how many cartons of raspberries Bill would need: 48 ounces / 8 ounces / carton = 6 cartons. Then multiply that number by the cost per carton to find the total cost of the raspberries: 6 cartons * $3 / carton = $18. Then subtract the cost of the raspberries from the cost of the blueberries to find the difference: $40 - $18 = $22. The answer is 22.
Q: Jackson is laying tile in a courtyard that measures 10 feet by 25 feet. He needs 4 tiles per square foot of space. 40% of the tiles are green marble that costs $3/tile, and the rest are red tile that costs $1.50/tile. How much does he pay total for tile?
A: First find the area of the courtyard: 10 feet * 25 feet = 250 feet. Then multiply the area by the number of tiles per square foot to find the total number of tiles needed: 250 feet * 4 tiles / square foot = 1000 tiles. Then multiply the number of tiles by the percentage that are green to find the total number of green tiles: 1000 tiles * 40% = 400 tiles. Subtract that number from the total number of tiles to find the number of red tiles: 1000 tiles - 400 tiles = 600 tiles. Multiply the number of red tiles by the price per red tile to find the cost of the red tiles: 600 tiles * $1.50 / tile = $900. Multiply the number of green tiles by the price per green tile to find the cost of the green tiles: 400 tiles * $3.00 / tile = $1200. Then add the cost of each type of tile to find the total cost: $900 + $1200 = $2100. The answer is 2100.
Question: Carly practices her butterfly stroke for 3 hours a day, 4 days a week, and her backstroke for 2 hours a day, six days a week. How much time does she spend practicing swimming in a month with 4 weeks?
Answer:
First find the total time Carly practices the butterfly stroke in a week: 3 hours / day * 4 days / week = 12 hours / week. Then find the total time Carly practices the backstroke stroke in a week: 2 hours / day * 6 days / week = 12 hours / week. Then add those two amounts of time to find her total practice time each week: 12 hours / week + 12 hours / week = 24 hours / week. Then multiply her weekly practice time by the number of weeks in a month to find her monthly practice time: 24 hours / week * 4 weeks / month = 96 hours / month. The answer is 96.
