Q: Sabrina is collecting herbs to make a poultice for her grandmother. She needs twice as many basil leaves as sage leaves and 5 fewer sage leaves than verbena leaves. If she needs 12 basil leaves, how many leaves total does she need?
A: First find the number of sage leaves Sabrina needs: 12 basil / 2 basil / sage = 6 sage. Then add 5 to find the total number of verbena leaves she needs: 6 sage + 5 = 11 verbena. Finally, add up all the different leaves to find the total number: 6 sage + 11 verbena + 12 basil = 29 leaves. The answer is 29.
Question: Leila spent $40 which is 1/4 of her money on a sweater. She was then left with $20 after spending the rest of her money on buying pieces of jewelry. How much more did Leila spend on jewelry than on the sweater?
Answer: Since 1 / 4 of her money is $40, then Leila originally had $40 x 4 = $160. $160 - $40 = $120 was left after buying a sweater. Since she is left with $20, Leila spent $120 - $20 = $100 on jewelry. Therefore, she spent $100 - $40 = $60 more for jewelry than on a sweater. The answer is 60.
[Question]A special balloon increases by two-fifths of its previous volume every hour when placed under water. If its original volume is 500cm³, what will its volume be after 2 hours underwater?
[Answer]In the first hour, the balloon will increase in volume by two - fifths of 500cm³ which is (2 / 5) * 500cm³ = 200cm³. After the first hour, it will have a volume of (500 + 200)cm³ = 700cm³. In the second hour, it will increase in volume by two - fifths of 700cm³ which is (2 / 5) * 700cm³ = 280cm³. After the second hour, it's volume will be (700 + 280)cm³ = 980cm³. The answer is 980.
Q: Andrew works in a company that provides a generous vacation allotment: for every 10 days worked, you get 1 vacation day. If last year Andrew worked 300 days and took 5 days off in March and twice as many in September, how many more vacation days can Andrew still take?
A: If for every 10 days worked Andrew earns 1 day of vacation, then over 300 days worked he would have earned 300 / 10 = 30 days of vacation. We know he took 5 days off in March and that in September twice as much. That means in September he took 5 * 2 = 10 days off. In total, Andrew has used 5 vacation days in March and another 10 in September. Therefore, he has used 5 + 10 = 15 vacation days. If Andrew earned 30 days of vacation but has only used 15, then he can still take another 30 - 15 = 15 days off. The answer is 15.
Question: Mr. Salazar had seven dozen oranges. He reserved 1/4 of it for his friend and was able to sell 3/7 of the remaining yesterday. Today, he saw four rotten oranges. How many oranges are left to be sold today?
Answer: Mr. Salazar had 7 x 12 = 84 oranges. He reserved 84 x 1 / 4 = 21 oranges for his friend. Ha had 84 - 21 = 63 oranges to be sold yesterday. But only 63 x 3 / 7 = 27 oranges were sold yesterday. So, he had 63 - 27 = 36 oranges left. Since four oranges are rotten, then only 36 - 4 = 32 oranges are left to be sold today. The answer is 32.
