Q: Five months ago, Mike earned 10 times more money than Fred. If his salary has increased by 40 percent now, and Fred's salary then was $1000, calculate Mike's salary now.
A: Five months ago, Mike earned ten times more money than Fred, and since Fred earned $1000, Mike earned 10 * 1000 = $10000 more than Fred. The total amount of money that Mike earned five months ago is $10000 + $1000 = $11000. Mikes salary has increased by 40 / 100 * $11000 = $4400. Mike's current salary is $11000 + $4400 = $15400. The answer is 15400.

Q: 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?
A: 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 is 2950.

Q: A crate can hold 20 kilograms of tomatoes. Tommy has 3 crates which he bought for $330. He wants to sell the tomatoes for $6 per 1 kilogram but 3 kilograms of tomatoes were rotten. How much will be Tommy's profit from selling those tomatoes?
A:
Tommy has a total of 20 x 3 = 60 kilograms of tomatoes. Only 60 - 3 = 57 kilograms can be sold. His earnings for the tomatoes will be $342. Thus, his profit will be $342 - $330 = $12. The answer is 12.
