Reasoning and answer: First she drives 2 hours * 60 mph = 120 miles. Then she drives 3 hours * 50 mph = 150 miles. The total miles driven is 120 + 150 = 270 miles. Jenna uses 270 / 30 = 9 gallons of gas. The cost of gas is 9 * $2 = $18.
The answer: 18

Question: Jenna is on a road trip. She drives for 2 hours at 60mph. She takes a bathroom break, and then she continues driving for 3 hours at 50 mph. She can drive for 30 miles on one gallon of gas. If one gallon of gas costs $2, how much money does she spend on gas for her trip?
Rene finished 30 x 4 = 120 pages in 240 minutes. Lulu finished 27 x 4 = 108 pages in 240 minutes. Cherry finished 25 x 4 = 100 pages in 240 minutes. Therefore they have finished a total of 120 + 108 + 100 = 328 pages in 240 minutes.
The answer: 328
Reverse engineering the question: Rene can finish reading 30 pages in 60 minutes. Lulu can read 27 pages in 60 minutes and Cherry can read 25 pages in 60 minutes. If they have been reading for 240 minutes now, how many pages have they finished reading in total?
Reasoning and answer: Ernesto = 11 + 3 = 14. Jayden = 14 / 2 = 7 in 3 years. Now = 7 - 3 = 4. Jayden is 4 years old.
The answer: 4

Question: In 3 years, Jayden will be half of Ernesto's age. If Ernesto is 11 years old, how many years old is Jayden now?
He ate 14 apples the first two weeks because 14 x 1 = 14. He ate 14 apples in the next three weeks because 14 = 14. He ate 42 apples in the final two weeks because 14 x 3 = 42. He ate 70 apples in total. He averaged 10 apples a week because 70 / 7 = 10.
The answer: 10
Reverse engineering the question: Archibald eats 1 apple a day for two weeks. Over the next three weeks, he eats the same number of apples as the total of the first two weeks. Over the next two weeks, he eats 3 apples a day. Over these 7 weeks, how many apples does he average a week?
Reasoning and answer: The second year, she quadrupled the number of statues in her front lawn, adding to the original 4 and bringing the total number to 4 * 4 = 16 statues. In the third year, she added another 12 statues, bringing the total number to 16 + 12 = 28 statues. But a hail storm broke 3, reducing the number to 28 - 3 = 25 statues. In the fourth year, she added twice as many new statues as had been broken the year before, adding 2 * 3 = 6 statues. Thus, the addition of these 6 statues brought the total number of statues to 25 + 6 = 31 statues.
The answer: 31

Question: Grandma Molly created statues of turtles for her front lawn. The first year, she created 4 statues and placed them on her lawn. The second year, she quadrupled the number of statues on her front lawn. In the third year, she added another 12 statues to the front lawn, but a hail storm broke 3 of the statues, which she threw away. In the fourth year, she added twice as many new statues as had been broken the year before. At the end of the four years, how many turtle statues were on her front lawn?
Reasoning and answer: The mural is 20 * 15 = 300 square feet. So it takes him 300 * 20 = 6000 minutes. So he paints it in 6000 / 60 = 100 hours. That means he charges 100 * 150 = $15000.
The answer: 15000
