Answer this question:The bakery makes 3 batches of baguettes a day. Each batch has 48 baguettes. After the first batch came out, he sold 37. After the second batch, he sold 52. After the third batch he sold 49. How many baguettes are left?
He makes 3 batches of baguettes a day, 48 per batch so he makes 3 * 48 = 144. He sells 37, then 52 then 49 baguettes for a total of 37 + 52 + 49 = 138. He had 144 to sell and he sold 138 so he has 144 - 138 = 6 left over.
The answer is 6.

Answer this question:Julia's internet speed is 20 MBps (megabytes per second). How many songs she can download in half an hour if the size per song is 5MB?
1 hour has 60 minutes, therefore 1 / 2 hour has 1 / 2 * 60 = 30 minutes. 1 minute has 60 seconds, therefore 30 minutes has 30 * 60 = 1800 seconds. If Julia's internet speed is 20MBps and each song has a size of 5MB, then it would take 5 / 20 = 1 / 4 seconds to download one song. If it takes 1 / 4 seconds to download 1 song, then in 1800 seconds, Julia could download 1800 / (1 / 4) = 1800 * 4 = 7200 songs.
The answer is 7200.

Answer this question:Carlo has a music recital next week. He practiced twice as long on Monday as on Tuesday. On Tuesday, he practiced 10 minutes less than on Wednesday. On Wednesday, he practiced 5 minutes more than on Thursday. On Thursday, he practiced for 50 minutes. If he needs to practice for a total of 5 hours that week, how long should Carlo practice on Friday?
On Wednesday, Carlo practiced for 50 + 5 = 55 minutes. On Tuesday, he practiced for 55 - 10 = 45 minutes. On Monday, he practiced for 45 x 2 = 90 minutes. So, Carlo practiced for a total of 90 + 45 + 55 + 50 = 240 minutes from Monday to Thursday. He needs to practice for a total of 60 x 5 = 300 minutes. Therefore, he should practice for 300 - 240 = 60 minutes on Friday.
The answer is 60.

Answer this question:John's piggy bank contains quarters, dimes, and nickels. He has three more dimes than quarters and 6 fewer nickels than quarters. If he has 63 coins, how many quarters does John have?
Let x represent the number of quarters John has. Nickels: x - 6. Dimes: x + 3. Total:x + x - 6 + x + 3 = 63. 3x - 3 = 63. 3x = 66. x = 22 quarters.
The answer is 22.
