Question: Tenisha had 40 dogs that she kept at home as pets. If 60% of them are female, and 3/4 of the female gives birth to 10 puppies each, calculate the total number of puppies that Tenisha remains with after donating 130 puppies to the church.
Answer: If Tenisha has 40 dogs, the number of female dogs is 60 / 100 * 40 = 24. 3 / 4 of the females give birth, meaning 3 / 4 * 24 = 18 female dogs gives birth to puppies. Since each dog that gave birth had 10 puppies, the number of puppies that were born is 18 * 10 = 180. After donating 130 puppies to the church, Tenisha remained with 180 - 130 = 50 puppies. The answer is 50.
[Question]Quinton is looking to add 4 fruit trees to his backyard. He wants to plant 2 apple trees that will be 10 feet wide each and need 12 feet between them. The peach trees will be closer to the house and will grow to be 12 feet wide and will need 15 feet between each tree. All told, how much space will these trees take up in his yard?
[Answer]Both apple trees will be 10 feet wide at maturity so they will be 2 * 10 = 20 feet wide. Quinton will need to leave 12 feet between these 2 trees so the apple trees will take up 20 + 12 = 32 feet. Both peach trees will be 12 feet wide at maturity so they will be 2 * 12 = 24 feet wide. Quinton will need to leave 15 feet between these 2 trees so the peach trees will take up 24 + 15 = 39 feet. Together, the apple trees will take up 32 feet and the peach trees will take up 39 feet so they will take 32 + 39 = 71 feet. The answer is 71.
Q: The average score on last week's Spanish test was 90. Marco scored 10% less than the average test score and Margaret received 5 more points than Marco. What score did Margaret receive on her test?
A: The average test score was 90 and Marco scored 10% less so 90 * .10 = 9 points lower. The average test score was 90 and Marco scored 9 points less so his test score was 90 - 9 = 81. Margret received 5 more points than Marco whose test score was 81 so she made 5 + 81 = 86 on her test. The answer is 86.
Question: Bill is trying to control the pests in his garden. Each spider he introduces eats 7 bugs, and each time he sprays the garden he reduces the total bug population to 80% of what it was previously. If the garden has 400 bugs to start, and Bill sprays once and introduces 12 spiders, how many bugs are left?
Answer: First find the total bug population after spraying: 80% * 400 bugs = 320 bugs. Then find the total number of bugs each spider eats: 12 spiders * 7 bugs / spider = 84 bugs. Then subtract that number from the number of bugs left after spraying to find final number of bugs: 320 bugs - 84 bugs = 236 bugs. The answer is 236.
[Question]On Rudolph's car trip across town, he traveled 2 more than 5 miles and encountered 3 less than 17 stop signs. How many stop signs per mile did Rudolph encounter on his trip across town?
[Answer]He traveled 2 more than 5 miles, or 5 + 2 = 7 miles. He encountered 3 less than 17 stop signs, or 17 - 3 = 14 stop signs. Thus, during his trip across town, Rudolph encountered 14 / 7 = 2 stop signs per mile. The answer is 2.
[Question]Evan owns 40 fewer books than the number he had 2 years ago. Evan will have 60 more than five times as many books as he owns now in five years. If Evan had 200 books two years ago, calculate the total number of books he will have in five years.
[Answer]
If Evan had 200 books two years ago, he currently has 200 - 40 = 160 books. In five years, Evan will have 60 more than 160 * 5 = 800 books which is the number he has now. This means Evan will have 800 + 60 = 860 books in five years. The answer is 860.
