24000=12000(1+ 4/100)^t    divide both sides by 12000

 

24000/12000 = (1 + .04)^t

 

2 = (1.04)^t     take the log of both sides

 

log (2)  = log (1.04)^t   and we can write

 

log (2)  = t * log(1.04)    divide both sides by log (1.04)

 

log(2) / log (1.04)  = t   = about 17.673

 

 

cool cool cool
