is it 22,149 or 22,054?

phi · Answer

2.9% is 0.029

we go down by  (1-0.029)* 29600
the first year
in general   29600* 0.971^n
where n is the number of years

@phi  i used that equation and got 22,054 and submitted it and it was wrong..

phi · Answer

do they say if you should round and if so, to what decimal place?

anonymous · Answer

nope it just says approximate.

phi · Answer

b. 21,874
c. 39,558
d. 22,054 
when i clicked D, it said it was incorrect

phi · Answer

I would take a screen shot and ask your teacher about this.  Unless there is more to the problem or a typo, the answer should be 22,054
