Q: Katy, Wendi, and Carrie went to a bread-making party. Katy brought three 5-pound bags of flour. Wendi brought twice as much flour as Katy, but Carrie brought 5 pounds less than the amount of flour Wendi brought. How much more flour, in ounces, did Carrie bring than Katy?
A: 160
Step-by-step reasoning process: Katy's three 5 - pound bags of flour weigh 3 * 5 = 15 pounds. Wendi brought twice as much flour as Katy, or 15 * 2 = 30 pounds of flour. Carrie brought 5 pounds less flour than Wendi, or 30 - 5 = 25 pounds of flour. Thus, Carrie brought 25 - 15 = 10 pounds of flour more than Katy. In ounces, the 10 pound difference is 10 * 16 = 160 ounces.

Q: Kate wants to buy a special pen as a gift for her friend. The pen costs $30, and Kate only has money for a third of that amount. How much more money does she need to buy the pen?
A: 20
Step-by-step reasoning process: Currently, Kate has only 1 / 3 * 30 = $10. That means Kate needs 30 - 10 = $20 more to buy the pen.

Q: Hansel makes $30,000 a year and just received a 10% raise. Gretel makes the same amount as Hansel but received a 15% raise. How much more money will Gretel make compared to Hansel?
A: 1500
Step-by-step reasoning process: Hansel makes $30,000 and received a 10% raise so his raise is 30,000 * .10 = $3,000.00. Hansel now makes 30,000 + 3,000 = $33,000 a year. Gretel makes $30,000 and received a 15% raise so her raise is 30,000 * .15 = $4,500.00. Gretel now makes 30,000 + 4,500 = $34,500 a year. If Gretel makes $34,500 a year and Hansel makes $33,000 then Gretel makes 34,500 - 33,000 = $1,500 more a year than Hansel.

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: 2950
Step-by-step reasoning process: 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.
