[Question]When it rains, the three holes in the garage roof leak water at different rates. The largest hole leaks at a rate of 3 ounces of water per minute. The medium-sized hole leaks water at one-half the rate of the largest hole. And the smallest hole leaks water at a rate of one-third the rate of the medium-sized hole. When it rains, what is the combined amount of water, in ounces, that leak from all three holes over a 2-hour time period?
[Answer]The medium - sized hole leaks at a rate of one - half that of the largest hole, or 3 / 2 = 1.5 ounces per minute. The small - sized hole leaks at a rate of one - third that of the medium - sized hole, or 1.5 / 3 = 0.5 ounces per minute. Combined, the three holes leak at a rate of 3 + 1.5 + 0.5 = 5 ounces per minute. Since one hour is 60 minutes, two hours is 2 * 60 = 120 minutes. In total, over the two hours, the three holes will leak a combined 120 * 5 = 600 ounces of water. The answer is 600.
Q: Bobby has 16 toy cars, and the number of cars he has increases by 50% every year. How many toy cars will Bobby have in three years?
A: In the first year, Bobby will acquire 16 * .5 = 8 new cars. After the first year, he will have a total of 16 + 8 = 24 cars. In the second year, Bobby will acquire 24 * .5 = 12 new cars. After the second year, he will have 24 + 12 = 36 cars in total. In the third year, Bobby will acquire 36 * .5 = 18 new cars. After the third year, he will have 36 + 18 = 54 cars in total. The answer is 54.
Question: There are 6 people going on an airplane trip. They each have 5 bags of luggage. Each of their bags weighs the maximum weight allowed, 50 pounds. The airplane can hold a total luggage weight of 6000 pounds. How many more bags at maximum weight can the plane hold?
Answer: Each person brought 5 bags * 50 pounds per bag = 250 pounds per person. There are 6 people * 250 pounds per person = 1500 pounds of luggage on the plane. The plan can hold 6000 pounds - 1500 pounds = 4500 pounds of luggage space left. The plane can hold an additional 4500 pounds / 50 pounds per bag = 90 pieces of luggage. The answer is 90.
[Question]Austin bought his seven friends each a robot. Each robot costs $8.75. He was charged $7.22 total for tax. He left with $11.53 in change. How much did Austin start with?
[Answer]First we need to find the total amount for the robots. 7 robots * $8.75 per robot = $61.25 in total. Now we need to add in the tax $61.25 for the robots + $7.22 for tax = $68.47 total spent in store. Now to find what was the beginning amount we take the $68.47 total spent in - store + $11.53 in change = $80 to start. The answer is 80.
Q: Jonah bought 6 pineapples for $3 each. Each pineapple could be cut into 12 pineapple rings. He sold 4 pineapple rings for $5 each. How much profit did Jonah make?

Question: Ali had a collection of seashells. He started with 180 seashells. He then gave away 40 seashells to his friends. He also gave 30 seashells to his brothers. If he sold half of the remaining seashells, how many seashells did he have left?
Answer:
When he gave 40 seashells to his friends, Ali had 180 - 40 = 140 seashells. When he gave another 30 seashells to his brothers, he had 140 - 30 = 110 seashells. He also sold half of the seashells, a total of 1 / 2 * 110 = 55 seashells. He was left with 110 - 55 = 55 seashells. The answer is 55.
