[Question]Ellie takes her little brother down to the pond to teach him how to skip stones. After he takes his first throw, she gives him pointers to improve his technique. His second throw skips two more times across the water than his first. His third throw skips twice as many times as his second. His fourth throw skips 3 fewer times than his third throw. His fifth throw skips one more time than the fourth throw. If his fifth throw skipped 8 times across the water, how many skips did he make in total between all of his throws?
[Answer]His fourth throw made 8 - 1 = 7 skips. His third throw made 7 + 3 = 10 skips. His second throw made 10 / 2 = 5 skips. His first throw made 5 - 2 = 3 skips. The total number of skips is 8 + 7 + 10 + 5 + 3 = 33 skips. The answer is 33.

[Question]Autumn was constantly misplacing her pencils. At the start of the school year, she purchased a pack of 20 pencils. In the first month of school, she misplaced 7 pencils, broke 3 pencils and had to throw them away, she found 4, and bought 2. How many pencils did Autumn have left?
[Answer]Autumn misplaced 7 and broke 3, so that lost her 7 + 3 = 10 pencils. Autumn found 4 pencils and bought 2, so she gained 4 + 2 = 6 pencils. She started with 20 pencils, lost 10 and gained 6 so she had 20 - 10 + 6 = 16 pencils left. The answer is 16.

[Question]Diana gets 30 minutes of video game time for every hour she reads. Her dad decided to raise her reward by 20%. Diana read for 12 hours this week. How many more minutes of video game time will she get as a result of her raise?
[Answer]Diana’s raise was 20% of her 30 - minute video game time, or 0.20 x 30 minutes = 6 minutes. Diana is now making 30 minutes + 6 - minute raise = 36 minutes for every hour she reads. Diana read 12 hours x 36 minutes of video game time, so she received 432 minutes of video game time after her raise. Before, if Diana read 12 hours x 30 minutes of video game time, she would have received 360 minutes. The amount she received after her raise, 432 minutes – 360 minutes at her old rate = 72 more minutes after her raise. The answer is 72.

[Question]A pound of strawberries costs $2.20 and a pound of cherries costs 6 times as much as strawberries. If Briget will buy 5 pounds of strawberries and 5 pounds of cherries, how much will it cost?
[Answer]
Five pounds of strawberries cost $2.20 x 5 = $11. A pound of cherries costs $2.20 x 6 = $13.20. Five pounds of cherries cost $13.20 x 5 = $66. Therefore, it will cost Briget a total of $11 + $66 = $77. The answer is 77.
