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?
Let's think: 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.

Hector purchased a container of gumballs. He gave 4 to Todd, then he gave twice as many as he had given Todd to Alisha, and then he gave 5 less than four times as many to Bobby as he had given to Alisha. If Hector had 6 gumballs remaining, what is the total number of gumballs that Hector purchased?
Let's think: Hector gave to Alisha twice as many as he had given Todd, for a total of 4 * 2 = 8 gumballs,. Hector gave 5 less than four times as many to Bobby as he had given to Alisha, or a total of (8 * 4) - 5 = 27 gumballs. If Hector had 6 gumballs remaining, he originally purchased 4 + 8 + 27 + 6 = 45 gumballs.. The answer is: 45.

The house is 20.5 feet by 10 feet. The porch measures 6 feet by 4.5 feet. The house and the porch need shingles. How many square feet of shingles will be needed to roof the house and the porch?
Let's think: House = 20.5 * 10 = 205 square feet. Porch = 6 * 4.5 = 27 square feet. 205 + 27 = 232 square feet. 232 square feet of shingles will be needed.. The answer is: 232.

Nathan plays amateur baseball. He played for 3 hours for two weeks, every day. His friend Tobias played for 5 hours every day, but only for one week. How many hours did Nathan and Tobias play in total?
Let's think:
Two weeks are 14 days, so Nathan played for 3 * 14 = 42 hours. Tobias played for 7 days, so he played a total of 5 * 7 = 35 hours. Nathan and Tobias played together for 42 + 35 = 77 hours.. The answer is: 77.
