Q: Janet has a business selling custom collars for dogs and cats. If it takes 18 inches of nylon to make a dog collar and 10 inches to make a cat collar, how much nylon does she need to make 9 dog collars and 3 cat collars?
A: First find the total number of inches of nylon used for the dog collars: 18 inches / dog collar * 9 dog collars = 162 inches. Then find the total number of inches of nylon used for the cat collars: 10 inches / cat collar * 3 cat collars = 30 inches. Then add the nylon needed for the cat and dog collars to find the total amount needed: 162 inches + 30 inches = 192 inches. The answer is 192.
Question: Holly wants to plant a wall of privacy trees along her fence line. Her fence is 25 yards long. At maturity, the trees she wants to plant will measure 1.5 feet wide. Right now, these trees are on sale for $8.00 apiece. How much will it cost her to plant a row of the trees to run the length of her fence?
Answer: 3 feet are in 1 yard and her fence is 25 yards long so her fence is 3 * 25 = 75 feet long. At maturity these trees will measure 1.5 feet and she needs them to run along her 75 - foot fence so she needs 75 / 1.5 = 50 trees. The trees cost $8.00 apiece and she needs 50 so 8 * 50 = $400.00 worth of trees. The answer is 400.
[Question]Sarah decided to pull weeds from her garden. On Tuesday she pulled 25 weeds. The next day she pulled three times the number of weeds she did the day before. On Thursday her allergies bothered her and she could only pull up one-fifth of the weeds she pulled on the day before. Finally, on Friday it rained for half the day and she managed to pull up 10 fewer weeds than she did on Thursday. In total, how many weeds did she pull up?
[Answer]On Wednesday she pulled 25 * 3 = 75 weeds. On Thursday she pulled 75 / 5 = 15 weeds. On Friday she pulled 15 - 10 = 5 weeds. In total she pulled 25 + 75 + 15 + 5 = 120 weeds. The answer is 120.
[Question]A soccer team had 24 players prepared for a soccer game. The first half saw 11 players start the game with 2 substitutions made. In the second half, the team made twice as many substitutions as it made in the first half. How many players on the team did not play that day?
[Answer]
With two substitutions, 11 + 2 = 13 players from the team played the game in the first half. In the second half, the team made twice the number of substitutions it made in the first half, a total of 2 * 2 = 4 substitutions. The total number of players who played the game is 13 + 4 = 17. If the soccer team had 24 players prepared for the soccer game, the number of players who did not play the game is 24 - 17 = 7 players. The answer is 7.
