Question: Jane's goal is to exercise 1 hour a day, 5 days a week. If she hits her goal weekly for 8 weeks, how many hours has Jane exercised?
Answer: Step-by-step reasoning process: Her goal is 1 hour a day for 5 days so on a weekly basis, she exercises 1 * 5 = 5 hours. If she works 5 hours a week for 8 weeks then she exercises 5 * 8 = 40 hours in 8 weeks.
So the answer is 40.

Question: In two years, Ophelia will be four times as old as Lennon. If Lennon is currently eight years old, how old is Ophelia?
Answer: Step-by-step reasoning process: In two years, Lennon will be 2 + 8 = 10 years old. Ophelia will be 4 * 10 = 40 years old in two years. Currently, Ophelia is 40 - 2 = 38 years old.
So the answer is 38.

Question: Carolyn wants to embroider her new jeans. She can sew 4 stitches/minute. A flower takes 60 stitches to embroider, a unicorn takes 180 stitches, and Godzilla takes 800 stitches. If Carolyn wants to embroider Godzilla crushing 3 unicorns and 50 flowers, how many minutes does she need to spend embroidering?
Answer: Step-by-step reasoning process: First find the total stitches in all the flowers by multiplying the number of stitches per flower by the number of flowers: 50 flowers * 60 stitches / flower = 3000 stitches. Then do the same for the total number of stitches in the unicorns: 3 unicorns * 180 stitches / unicorn = 540 stitches. Then add the number of stitches for all the flowers, unicorns, and Godzilla to find the total number of stitches: 800 stitches + 540 stitches + 3000 stitches = 4340 stitches. Finally, divide the total number of stitches by the number of stitches Carolyn can make per hour to find how many hours she spends embroidering: 4340 stitches / 4 stitches / minute = 1085 minutes.
So the answer is 1085.

Question: During a unit on probability, a teacher surveys her class asking her students two questions. The first question was whether they prefer dogs or cats, and the second question was whether they movies or video games. Of the 30 students in her class, 50% chose dogs and video games as their two answers, while 10% chose dogs and movies as their two answers. In total, how many students in this teacher's class prefer dogs over cats?
Answer:
Step-by-step reasoning process: The 50% of the class that chose dogs and video games amounts to 30 * 0.5 = 15 students who prefer dogs over cats. Similarly, the 10% that chose dogs and movies amount to 30 * 0.1 = 3 students who prefer dogs over cats. Because these are the only two ways that a student could indicate their preference for dogs, and because these groups do not overlap, a total of 15 + 3 = 18 students favor dogs over cats in this teacher's class.
So the answer is 18.
