Question: Kate has to fill 52 balloons for the party. Each balloon holds 5 gallons of air. For the first 10 minutes, she can fill the balloons at a rate of 8 gallons of air per minute. For the next five minutes, she fills them at half that rate. After that, she fills the rest of the balloons at a rate of 2 gallons of air per minute. How many minutes will it take her to fill all of the balloons?
Answer: Step-by-step reasoning process: She needs to fill a total of 52 * 5 = 260 gallons of air. In the first ten minutes, she fills 8 * 10 = 80 gallons of air. For the next five minutes, she fills 8 / 2 * 5 = 20 gallons of air. That leaves her with 260 - 80 - 20 = 160 gallons of air to fill. It will take her 160 / 2 = 80 more minutes to fill the rest of the balloons. The total time to fill all of the balloons is 10 + 5 + 80 = 95 minutes.
So the answer is 95.

Question: Solomon collected three times as many cans as Juwan. Levi collected half of what Juwan collected. Solomon collected 66 cans. How many cans did the boys collect in all?
Answer: Step-by-step reasoning process: Solomon is 3 * Juwan so Juwan is 1 / 3 of Solomon = 66 / 3 = 22. Levi collected half of 22 = 11. Combined the boys collected 66 + 22 + 11 = 99 cans in all.
So the answer is 99.

Question: Jack leaves his bathtub's faucet dripping at a rate of 40 ml/minute. Water evaporates from the bathtub at a rate of 200 ml/hour. If he leaves the water running for 9 hours, then dumps out 12 liters, how many milliliters of water are left in the bathtub?
Answer: Step-by-step reasoning process: First find how much water fills the bathtub per hour: 40 ml / minute * 60 minutes / hour = 2400 ml / hour. Then subtract the water that evaporates to find the total amount of water added per hour: 2400 ml / hour - 200 ml / hour = 2200 ml / hour. Then multiply that amount by the number of hours to find the total amount of water in the tub: 2200 ml / hour * 9 hours = 19800 ml. Then find the number of milliliters in 12 liters: 12 liters * 1000 ml / liter = 12000 ml. Then subtract the water Jack removes from the total amount of water to find the remaining amount of water: 19800 ml - 12000 ml = 7800 ml.
So the answer is 7800.

Question: Estevan has 24 blankets. One-third of the blankets have polka-dots. For his birthday, his mother gives him 2 more polka-dot print blankets. How many polka-dot blankets does Estevan have in total?
Answer:

So the answer is 10.
