[Question]A snack machine accepts only quarters. Candy bars cost ¢25, each piece of chocolate costs ¢75, and a pack of juice costs ¢50. How many quarters are needed to buy three candy bars, two pieces of chocolate, and one pack of juice?
[Answer]Three candy bars cost ¢25 x 3 = ¢75. Two pieces of chocolate cost ¢75 x 2 = ¢150. So, the total amount needed to buy those is ¢75 + ¢150 + ¢50 = ¢275. Since a quarter is equal to ¢25, therefore ¢275 / ¢25 = 11 quarters are needed. The answer is 11.
Q: Sadie, Ariana and Sarah are running a relay race. Each part of the race is a different length and covers different terrain. It takes Sadie 2 hours to run through the forest at an average speed of 3 miles per hour. Ariana sprints across the open field on her section at 6 miles per hour for half an hour. If Sarah runs along the beach at four miles per hour and their total time for the race is four and half hours, what is the total distance of the race?
A: Sadie ran for 3 miles / hour * 2 hour = 6 miles. Ariana covered a distance of 6 miles / hour * (1 / 2) hour = 3 miles. Sarah ran for 4.5 hours – 2 hours – 0.5 hours = 2 hours. In this time, Sarah traveled a distance of 4 miles / hour * 2 hours = 8 miles. The total distance for the race was 6 miles + 3 miles + 8 miles = 17 miles. The answer is 17.
Question: 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?
Answer: 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]A school bus has 4 columns and 10 rows of seats. If the school has 6 buses, how many students can the buses accommodate?

Q: If olivine has 5 more precious stones than agate and diamond has 11 more precious stones than olivine, how many precious stones do they have together if agate has 30 precious stones?
A: Since Agate has 30 precious stones and Olivine has 5 more precious stones, then Olivine has 30 + 5 = 35 precious stones. The total number of stones Olivine and Agate has is 35 + 30 = 65. Diamond has 11 more precious stones than Olivine, who has 35 stones, meaning Diamond has 35 + 11 = 46 precious stones. In total, they all have 65 + 46 = 111 precious stones. The answer is 111.
