Question: Carly is making a beaded corset. She's going to add 50 rows of purple beads with 20 beads per row, 40 rows of blue beads with 18 beads per row, and 80 gold beads. If beads cost $1 per 10 beads, how much do all the beads she bought cost?
Answer: First find the total number of purple beads Carly needs: 50 rows * 20 beads / row = 1000 beads. Then find the total number of blue beads Carly needs: 40 rows * 18 beads / row = 720 beads. Then add the number of each color she needs to find the total number she needs: 1000 beads + 720 beads + 80 beads = 1800 beads. Then divide the number of beads by 10 to find the cost: 1800 beads / 10 beads / $1 = $180. The answer is 180.
[Question]Todd borrowed $100 from his brother to start a snow-cone stand. He has to repay him $110 as soon as he can. Todd spent $75 on ingredients for the snow cones. He sells 200 of them for $.75 each. After he pays back his brother, how much money does Todd have?
[Answer]Todd has $25 left after buying ingredients because 100 - 75 = 25. Todd made $150 selling snow - cones because 200 x .75 = 150. Todd has $175 before he pays his brother back because 25 + 150 = 175. After Todd pays his brother back he has $65 because 175 - 110 = 65. The answer is 65.
Q: Dr. Banks had 330 toothbrushes to give away to his patients. He gave away 53 toothbrushes in January. He gave away 67 toothbrushes in February. In March he gave away 46 toothbrushes. In April and May, he gave away the remaining toothbrushes, half each month. How many more toothbrushes did Dr. Banks give out in the busiest month versus the slowest month?
A: Through March, Dr. Banks gave out 53 + 67 + 46 = 166 toothbrushes. Before giving away toothbrushes in April, he had 330 - 166 = 164 toothbrushes remaining. Between April and May, he gave out the remaining 164 / 2 = 82 toothbrushes each month. Dr. Banks gave 82 toothbrushes in his busiest month and 46 toothbrushes during the slowest month. The difference would be 82 - 46 = 36 more toothbrushes in the busiest month. The answer is 36.
Question: Brian likes to read books. He read one book that had 20 chapters, two books that had 15 chapters each, and one book that had half the chapters of the three previous books put together. How many chapters of books did Brian read?
Answer: Brian read two books with 15 chapters, so he read 2 * 15 = 30 chapters. He also read a book with 20 chapters, bringing the total for the first three to 30 + 20 = 50 chapters. He then read a book with half the chapters of his cumulative total so far, so it had 50 / 2 = 25 chapters. In total, he read 30 + 20 + 25 = 75 chapters. The answer is 75.
[Question]It takes 1 person working 10 hours to figure out the solution to a math problem. If you add a second person who's equally good at math, how long will the two of them have to work to solve the same problem?
[Answer]Since you're doubling the number of people working on the task, that means you will be able to reduce the amount of time worked in half if they're of equal skill. Therefore, you take the original time of 10 hours and perform 10 / 2 = 5 hours spent working on the problem. The answer is 5.
[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]

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

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.
