You can put this solution on YOUR website!
1 week = 7 days

2 weeks = 14 days

-----------------------------


The equation we'll use is

A+=+P%2A2%5Et

where

A = final amount
P = initial amount
t = time in days

In this case,

A = unknown (for now)
P = 4 (start out with 4 bugs)
t = 14 (14 days have elapsed)


A+=+P%2A2%5Et

A+=+4%2A2%5E14

A+=+4%2A16384

A+=+65536


So you currently have 65,536 bugs.
