Reasoning & answer: CoT: Ann and Becky have worked for 8 hours each, so both of them worked for 2 people * 8 hours / person = 16 hours. All three of them, including Julia, were working for 16 hours + 6 hours = 22 hours. So in total, they all have served 7 customers / hour * 22 hours = 154 customers in one day.
The answer: 154

Reasoning & answer: CoT: The grill burned 3 * 60 = 180 coals. It takes 20 minutes to burn 15 coals, so the grill ran for 180 / 15 * 20 = 240 minutes.
The answer: 240

Reasoning & answer: CoT: Aisha starts with 500 songs + 500 songs = 1000 songs added to her mp3 player in the first two weeks. After that Aisha adds twice that amount to her mp3 player, 1000 x 2 = 2000 songs added. She now has 1000 + 2000 = 3000 songs on her mp3 player. However, she decides she wants to remove 50 of them, 3000 - 50 = 2950 songs on her mp3 player.
The answer: 2950
Question: Aisha enjoys listening to music on her mp3 player. She starts with 500 songs on her mp3 player, then adds another 500 the week after that. She realizes her mp3 player has a large capacity for storing songs so she adds twice the amount she already had on her mp3 player. After a while, though, she decides that she doesn't like 50 of the songs and removes them. How many songs are on Aisha's mp3 player now?

Reasoning & answer: CoT: There are 80 / 100 * 10 = 8 more purple flowers than yellow flowers. So in Mark's garden, there are 10 + 8 = 18 purple flowers. Purple and yellow flowers sum up to 10 + 18 = 28 flowers. That means in Mark's garden there are 25 / 100 * 28 = 7 green flowers. So in total Mark has 28 + 7 = 35 plants in his garden.
The answer: 35
