Reasoning and answer: There are 2 classes x 5 days = 10 classes on weekdays. There are 4 classes x 2 days = 8 classes on weekends. There are a total of 10 + 8 = 18 classes per week. So each week, 18 x 5 = 90 people can take classes. Thus, 90 x 3 = 270 people can take classes in 3 weeks.
The answer: 270

Beatrice looked at 3 x 8 TVs at an online store = 24 TVs. She looked at 8 TVs in person + 24 TVs online = 32 TVs. Beatrice looked at 42 TVs in all - the 32 she looked at = 10 TVs she looked at on an auction site.
The answer: 10
Reverse engineering the question: Beatrice is shopping for a new TV. First she looks at 8 TVs at one store in person. Then she looks at three times as many TVs at an online store. She looks at more TVs on an auction site online. If Beatrice looked at 42 TVs in all, how many did look at on the auction site?


Reasoning and answer: Paityn has a total of 20 hats + 24 hats = 44 hats. The number of red hats that Zola has is 4 / 5 * 20 hats = 16 hats. Zola also has 2 * 24 hats = 48 blue hats. Zola has a total of 48 hats + 16 hats = 64 hats. When they combine their hats, they have 64 hats + 44 hats = 108 hats. If they share the hats equally, each get 108 hats / 2 people = 54 hats / person.
The answer: 54

The answer: 51

Reasoning and answer: The clothes take 30 minutes to wash and the towels take twice as long, 30 x 2 = 60 minutes to wash the towels. The sheets take 15 minutes less than the towels, 60 - 15 = 45 minutes to wash the sheets. It takes 30 minutes + 60 minutes + 45 minutes = 135 minutes to wash everything.
The answer: 135
