Lisa walks 10 meters each minute. Every day, she walks for an hour. How many meters will Lisa walk in two days? Give the rationale and then the answer.
Let's think step by step. Since there are 60 minutes in 1 hour, then Lisa walks for 1 x 60 = 60 minutes every day. For 60 minutes, Lisa walks 60 x 10 = 600 meters. Thus, she walks for 600 x 2 = 1200 meters in two days.. The answer is: 1200.

At Kaleb's Restaurant, a group with six adults and two children came in to eat. If each adult meal cost six dollars and each children's meal was $4, and every person ordered a soda for $2 how much was the bill? Give the rationale and then the answer.
Let's think step by step. The cost for adult meals is 6 adults * $6 = $36. The cost for children's meals is 2 children * $4 = $8. The total people ordering drinks is 6 + 2 = 8. The cost for drinks is 8 people * $2 = $16. The total cost for the meal is $36 + $8 + $16 = $60.. The answer is: 60.

Annie does a survey of the sixth-grade classes to see who prefers pretzels to goldfish. In Miss Johnson's class, 1/6 of the students preferred goldfish. In Mr. Feldstein's class, 2/3rds of the students preferred goldfish. In Ms. Henderson's class, 1/5 of the students prefer goldfish. If each class has 30 students, how many people total prefer goldfish? Give the rationale and then the answer.
Let's think step by step. First find the number of students in Mr. Feldstein's class who prefer goldfish: 2 / 3 * 30 students = 20 students. Then find the number of students in Mr. Feldstein's class who prefer goldfish: 1 / 6 * 30 students = 5 students. Then find the number of students in Ms. Henderson's class who prefer goldfish: 1 / 5 * 30 students = 6 students. Then add the number of students from each class who prefer goldfish to find the total: 20 students + 5 students + 6 students = 31 students.. The answer is: 31.
