Q: Bronson decides to collect Oak Leaves from around his Neighborhood. He collects 12 on Thursday and 13 on Friday. 20% are Brown and 20% are Green. The rest are yellow. How many yellow leaves does he collect?
A: He collects 25 leaves because 12 + 13 = 25. 60% of them are yellow because 100 - 20 - 20 = 60. He collects 15 yellow leaves because 25 x .6 = 15. The answer is 15.
Question: Aaron, Henry's brother, is 15 years old. Henry's sister is three times as old as Aaron. Henry is four times as old as his sister. What's the combined age of the siblings?
Answer: If Aaron is 15 years old, and his sister is 3 times as old as him, then the sister is 3 * 15 = 45 years old. Together, Aaron and his sister have a total age of 45 + 15 = 60 years. Henry is four times as old as the sister, meaning he is 45 * 4 = 180 years old. The three siblings together have a total age of 60 + 180 = 240 years. The answer is 240.
[Question]Marie has 4 notebooks with 20 stamps each. She also has two binders with 50 stamps each. If she decides to only keep 1/4 of the stamps, how many stamps can she give away?
[Answer]Marie has 4 x 20 = 80 stamps from her notebooks. And she has 2 x 50 = 100 stamps from her binders. So she has a total of 80 + 100 = 180 stamps. Marie decided to keep 180 x 1 / 4 = 45 stamps only. Therefore, she can give away 180 - 45 = 135 stamps. The answer is 135.
Q: Marcus takes a deck of standard playing cards and takes out all the face cards and the 8's. Mark picks a card at random and then replaces it 36 times. How many times should he expect to pick a card that's both red and has a number divisible by 3?
A: Without the face cards and the 8's, there are 9 cards of each suit. Half these cards are red, and 3 / 9 have numbers divisible by 3, so the odds of drawing a card divisible by 3 are 1 / 3. Multiply the odds of drawing a red card by the odds of drawing a card divisible by 3 to find the odds of both things happening: 1 / 3 * 1 / 2 = 1 / 6. Finally, multiplying the probability of drawing a red / 3 - divisible card by the number of cards Mark draws to find how many he should expect to meet his criteria: 1 / 6 * 36 cards = 6 cards. The answer is 6.
Question: A man owned 1/2 of a lot. He sold 1/10 of his share for the amount of $460. What is the worth of the entire lot?
Answer: If 1 / 10 of the man's lot is equal to $460, then the man's land is worth $460 x 10 = $4600. Since 1 / 2 of the whole lot is worth $4600, then the whole lot is worth $4600 x 2 = $9200. The answer is 9200.
Q: Lance has 70 cents, Margaret has three-fourths of a dollar, Guy has two quarters and a dime, and Bill has six dimes. How many cents do they have combined?
A:
Margaret has 100 * 0.75 = $0.75. Guy has $0.25 + $0.25 + $0.10 = $0.60. Bill has 6 * $0.10 = $0.60. Lance, Margaret, Guy and Bill have $0.70 + $0.75 + $0.60 + $0.60 = $2.65. Thus they have $2.65 * 100 = 265 cents. The answer is 265.
