## Ninja Calculations

I decided to type up the equations used to determine
both the ninja efficiency and the actual cost of a ninja.
(I hope you appreciate this. you have no idea how difficult it is to
type mathematical equations using pico)

Here's the exact mathematical equations. Specially derived using the
ninja constant - Ö(n).

N
efficiency = --- x 100
Q

where:

N = # of ninjas received during a certain buying period

Q = # of quarters it took to get N ninjas

*example:*
say you put 10 quarters in. You get the following:

- orange nunchuka

- sticker of the white power ranger

- yellow ninja with tool

- sticker featuring a group picture of the MMPR

- Wile E. Coyote magic eye sticker

- blue weeny swords

- sticker of white power ranger

- sticker of green power ranger

- yellow grappling hook

- pink throwing star

so the ninja efficiency would be:

5
efficiency = ---- x 100 = 0.5 x 100 = 50%
10

**Actual Ninja Cost**

The equation for the ninja cost is given by:

(cost per item)
cost(ninja) = ------------------
ninja efficiency

so, using the efficiency from the previous example, your average cost of
the ninja is actually:

$0.25
cost(ninja) = ------- = $0.50 = 50 cents per each
0.5
