490*(1-0.09)^T
T is year. Plug 5 into it to answer the question.
Start/All programs/Accessories/Calculator, it even has scientific mode.

P(t)=490*.91^t
P(5)=490*.91^5=306

precisely, you realize i became in common words discussing that, this very evening with a can of lager with a damaged ring pull. i imagine the can of Export surmised that there are slightly extra cons with exponential purposes. AP: i'm no longer keen on both yet i am going to bypass with bunnies, exponential of route.

exponential function
a(1 - b)^c = d
where a = initial amount
b= percent
c=time
d= final amount
490(1 - 0.09)^5 = ??
