Question: Carly is trying to get in shape to try out for the soccer team. She starts by running 2 miles a week. The second week, she runs twice as long plus 3 extra miles per week. The third week she runs 9/7 as much as she ran the second week. The week after that, she sprains her ankle and has to reduce her running time by 5 miles per week. How many miles did she run the week she was injured?
Answer: First find how long Carly runs the second week: 2 miles * 2 + 3 = 7 miles. Then find how long she runs in the third week: 9 / 7 * 7 miles = 9 miles. Then subtract the 5 miles reduction from when she was injured: 9 miles - 5 miles = 4 miles. The answer is 4.
[Question]Martha receives a daily allowance of $12. She decides to save half of this amount every day. In the first week she kept her commitment with the exception of one day when she saved only a quarter of this amount. How much has she saved at the end of this week?
[Answer]Half of $12 is (1 / 2) * $12 = $6. There are 7 days in a week so if she saved half every day except one then she saved half for 7 - 1 = 6 days. She saved $6 for 6 days for a total of $36. A quarter of $12 is (1 / 4) * $12 = $3. She saved a quarter once for a total savings of $3 + $36 = $39. The answer is 39.
Q: A monkey swings from branch to branch at an average distance of 1.2 meters per second. How far will a monkey swing in meters if it consistently swings from branches for 30 minutes?
A: If a monkey swings 1.2 meters a second then a monkey can swing 1.2 meters / second * 60 seconds / minute = 72 meters in a minute. If a monkey swings 72 meters in a minute then a monkey can swing 72 meters / min * 30 minutes = 2,160 meters in 30 minutes. The answer is 2160.

[Question]Suzanne wants to raise money for charity by running a 5-kilometer race. Her parents have pledged to donate $10 for her first kilometer and double the donation for every successive kilometer. If Suzanne finishes the race, how much money will her parents donate?
[Answer]
For the 2nd kilometer, the donation will be $10 * 2 = $20. For the 3rd kilometer, the donation will be $20 * 2 = $40. For the 4th kilometer, the donation will be $40 * 2 = $80. For the final kilometer, the donation will be $80 * 2 = $160. For the entire race the donation will be $10 + $20 + $40 + $80 + $160 = $310. The answer is 310.
