Geocache Description:

Micro cache (Magnetic Key Holder) in Bellevue, Nebraska that requires you to solve a couple quantitative methods problems to find. You're going to have to dust off those math skills and dig out that old Quantitative Methods textbook from college (or brush up on your Google skills). Due to all the recent rains, I have changed the terrain rating. The small hill used to access the cache has eroded some, I also repositioned the cache slightly so that it's easier to reach.

Coordinates listed above will only get you within ½ mile of the actual cache. To find the actual coordinates, please solve the problems below:

W 095° 54.AAA
N 41° 08.BBB

Using the data in the box below: To determine the hidden portion of the WEST coordinate you will need to find the optimal order quantity using the Economic Order Quantity (EOQ) model.

Using the data in the box below: To determine the hidden portion of the NORTH coordinate you will need to determine the reorder point and subtract it from the optimal order quantity that you determined when solving the west coordinate problem.


Annual Demand: 2,437
Order Cost: $15 per order
Carrying/Holding Cost: 10¢ per unit per year
Working Days per Year: 240
Lead Time: 4.5 days


The cache is near a very busy road and close to a playground. I don't want the cache stolen or vandalized any more than you want to log a DNF. Please watch for muggles as best you can, use stealth, and rehide the cache well!!! It won't be easy in this location, but do your best.
