[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: Three companies, A, B, and C, each purchased 10 ad spaces on a newspaper, with each ad space having a size of 12 foot by 5-foot rectangle. If each square foot ad was charged at $60, how much money did the three pay for the ads combined?
Answer: A size 12 foot by 5 - foot rectangle ad takes 12 * 5 = 60 square feet since the area of a rectangle is l * w. If each company bought 10 ad spaces, the total area that their ads took is 60 * 10 = 600 square feet. If each square foot of ad space was charged at $60, 600 square feet of ads cost $60 * 600 = $36000. If all three companies each purchased an equal number of ad space, together they paid $36000 * 3 = $108000. The answer is 108000.
[Question]A married couple opened a savings account. The wife committed to saving $100 every week while the husband committed to saving $225 every month. After 4 months of savings, they decided to invest half of their money in buying stocks. Each share of stocks costs $50. How many shares of stocks can they buy?
[Answer]The wife saves $100 / week x 4 weeks / month = $400 a month. Together, the wife and husband save $400 / month + $225 / month = $625 / month. In 4 months, their total savings is $625 / month x 4 months = $2500. They are going to invest $2500 / 2 = $1250. So, they can buy $1250 / $50 / share = 25 shares of stocks. The answer is 25.
Q: A tree had 1000 leaves before the onset of the dry season, when it sheds all its leaves. In the first week of the dry season, the tree shed 2/5 of the leaves. In the second week, it shed 40% of the remaining leaves. In the third week, the tree shed 3/4 times as many leaves as it shed on the second week. Calculate the number of leaves the tree hadn't shed by the third week.
A: In the first week, the tree shed 2 / 5 * 1000 = 400 leaves. The number of leaves remaining on the tree at the end of the first week is 1000 - 400 = 600. In the second week, the tree shed 40 / 100 * 600 = 240 leaves. The number of leaves remaining on the tree is 600 - 240 = 360. The third week the tree shed 3 / 4 of its leaves, a total of 3 / 4 * 360 = 270 leaves. The number of leaves remaining on the tree is 360 - 270 = 90 leaves. The answer is 90.
Question: Holly loves to drink chocolate milk. With breakfast, she drinks 8 ounces of chocolate milk before leaving for work. During her lunch break, she buys a new 64-ounce container of chocolate milk and then drinks 8 ounces of it. With dinner, she drinks another 8 ounces of chocolate milk. If she ends the day with 56 ounces of chocolate milk, how many ounces of chocolate milk did she begin the day with?
Answer:
Before dinner, she had 56 + 8 = 64 ounces of CM. Before drinking 8 ounces of CM during lunch, she had 64 + 8 = 72 ounces of CM. Before buying 64 ounces of CM, she had 72 - 64 = 8 ounces of CM. And before breakfast, she had 8 + 8 = 16 ounces of chocolate milk. The answer is 16.
