Cache is not at the posted coordinates, but you already knew that. To find the cache and sign the log, a simple math problem is yours to solve. My Middle School GT student group solved this puzzle in about 5 minutes. I must admit, I thought it would take longer. After they solved it, they said, "This would be a fun mystery cache for your geocaching game!" So, here it is.
Two women went into a local bank with a thousand dollars, in one dollar bills. They also had 10 drawstring backpacks. The bank manager was intrigued. "What can I do for you ladies?" he asked. "We would appreciate it," one of the woman responded. "if you could place this money in these 10 bags in such a way that if we call and ask for any amount of money up to $1,000, you could simply hand over one or more of the bags, without opening any of the bags, and give us the exact amount we called for."
"Why of course," said the bank manager, "that would not be a problem at all." The women handed over the money and the bags, told the manager they would be in touch, and left the bank. The manager did some quick calculations and placed the money in the 10 bags, numbered them from 1 to 10 (1 being the smallest amount, 10 the largest), and placed them in the safe. He could not imagine why anyone would want their money divided in such a way, but he was a manager known for his discretion.
To find the coordinates for the cache, simply figure out how much money is in each bag. The final coordinates are as follows:
Latitude: Subtract the amount in bag #10 from the posted coordinates, after the decimal.
Longitude: Multiply the amount in bag #8 by 6, add this product to the posted coordinates, after the decimal.
The students wanted to do a devious hide, but I dissuaded them and we hid it in a spot fairly familiar to cachers. There is parking nearby. Some stealth should be employed. My group thought the puzzle was easy, so they said no hint.
