[Question]Prudence was starting a cupcake business. She figured that each cupcake cost $0.75 to make. The first 2 dozen that she made burnt and she had to throw them out. The next 2 came out perfectly and she ended up eating 5 cupcakes right away. Later that day she made 2 more dozen cupcakes and decided to eat 4 more. If she sells the remaining cupcakes at $2.00 each, how much is her net profit?
[Answer]She burnt 2 dozen, cooked 2 dozen and then another 2 dozen that evening. So she made 2 + 2 + 2 = 6 dozen cupcakes. Each dozen makes 12 cupcakes, so she made 6 * 12 = 72 cupcakes. She threw away 2 dozen cupcakes, so 2 * 12 = 24 cupcakes. She made 72, threw away 24, ate 5 and then ate another 4 so she had 72 - 24 - 5 - 4 = 39 cupcakes left. She sells the 39 cupcakes at $2.00 each so she earned 39 * 2 = $78.00. She made 72 cupcakes at a cost of $0.75 each for a total cost of 72 * $0.75 = $54.00. If she made $78 on the remaining cupcakes and it cost her $54.00 to make all of the cupcakes then her profit is $78 - $54 = $24.00. The answer is 24.
Q: At the Delicious Delhi restaurant, Hilary bought three samosas at $2 each and four orders of pakoras, at $3 each, and a mango lassi, for $2. She left a 25% tip. How much did the meal cost Hilary, with tax, in dollars?
A: The samosas cost 3 * 2 = 6 dollars each. The pakoras cost 4 * 3 = 12 dollars each. The food came to 6 + 12 + 2 = 20 dollars. The tip was an additional 20 * .25 = 5 dollars. The total is 20 + 5 = 25. The answer is 25.
Question: Cary is 72 inches tall. Her younger brother Bill is half her height, and her younger sister Jan is 6 inches taller than Bill. How tall is Jan?
Answer: First find Bill's height by dividing Cary's height by 2: 72 inches / 2 = 36 inches. Then add six inches to find Jan's height: 36 inches + 6 inches = 42 inches. The answer is 42.
[Question]Tom fills a 250 pound sandbag 80% full. But the filling material he is using is 40% heavier than sand. How much does the bag weigh?
[Answer]The bag full of sand would weigh 250 * .8 = 200 pounds. The filling material would make it 200 * .4 = 80 pounds heavier. So it weighs 200 + 80 = 280 pounds. The answer is 280.
Q: Carolyn wants to embroider her new jeans. She can sew 4 stitches/minute. A flower takes 60 stitches to embroider, a unicorn takes 180 stitches, and Godzilla takes 800 stitches. If Carolyn wants to embroider Godzilla crushing 3 unicorns and 50 flowers, how many minutes does she need to spend embroidering?
A: First find the total stitches in all the flowers by multiplying the number of stitches per flower by the number of flowers: 50 flowers * 60 stitches / flower = 3000 stitches. Then do the same for the total number of stitches in the unicorns: 3 unicorns * 180 stitches / unicorn = 540 stitches. Then add the number of stitches for all the flowers, unicorns, and Godzilla to find the total number of stitches: 800 stitches + 540 stitches + 3000 stitches = 4340 stitches. Finally, divide the total number of stitches by the number of stitches Carolyn can make per hour to find how many hours she spends embroidering: 4340 stitches / 4 stitches / minute = 1085 minutes. The answer is 1085.
Question: Sarah buys 20 pencils on Monday. Then she buys 18 more pencils on Tuesday. On Wednesday she buys triple the number of pencils she did on Tuesday. How many pencils does she have?
