[Question]Caleb and Cynthia are filling up their inflatable pool with water using buckets. They fill their buckets at the spigot and carry them to the pool. Caleb can add 7 gallons from his bucket and Cynthia can add 8 gallons from her bucket each trip. It will take 105 gallons to fill the pool. How many trips will it take for Caleb and Cynthia to fill the pool with their buckets?
[Answer]Each trip, they add Caleb’s 7 gallons + Cynthia’s 8 gallons = 15 gallons. Since they are adding 15 gallons every trip, to fill the 105 - gallon pool, it would take 105 / 15 = 7 trips. The answer is 7.
Q: Linda bought two coloring books at $4 each, 4 packs of peanuts at $1.50 each pack, and one stuffed animal. She gave the cashier $25 and got no change. How much does a stuffed animal cost?
A: The two coloring books amount to 2 x $4 = $8. The 4 packs of peanuts amount to 4 x $1.50 = $6. The total cost for the coloring books and peanuts is $8 + $6 = $14. Thus, the stuffed animal cost $25 - $14 = $11. The answer is 11.
Question: Carla's sheepdog rounded up 90% of her sheep, but the remaining 10% wandered off into the hills. If there are 81 sheep in the pen, how many are out in the wilderness?
Answer: First find the total number of sheep by dividing the number rounded up by 90%: 81 sheep / .9 = 90 sheep. Then multiply that number by 10% to find the number that are in the hills: 90 sheep * 10% = 9 sheep. The answer is 9.
[Question]In her first term, Governor Sandoval gave twice as many commencement addresses as Governor Hawkins. Governor Sloan gave ten more commencement addresses than Governor Sandoval in the same amount of time. If Governor Sandoval gave 12 commencement addresses, how many commencement addresses did the three of them give altogether?
[Answer]Since Governor Sandoval gave 12 commencement addresses, twice the number that Governor Hawkins gave, Governor Hawkins gave 12 / 2 = 6 commencement addresses. The two of them gave 6 + 12 = 18 commencement addresses in total. Governor Sloan gave ten more commencement addresses than Governor Sandoval, a total of 12 + 10 = 22 commencement addresses. The three of them gave 22 + 18 = 40 commencement addresses. The answer is 40.
[Question]A store gives a 10% discount for the amount of the sell that was over $1000. John buys 7 items that each cost $200. What does his order cost after the discount?
[Answer]
His order came out to 7 * 200 = $1400. So there was 1400 - 1000 = $400 that qualified for the discount. So his discount saved 400 * .1 = $40. So his purchase came out to 1400 - 40 = $1360. The answer is 1360.
