Hi, In General A+=+P%281%2Br%2Fn%29%5E%28nt%29

If 10000 pesos is invested at 10% compounded quarterly ,

A = Accumulated Amount

P= principal = 10000

r= annual rate = .10

n= periods per year = 4

t= years =

A+=+P%281.025%29%5E%284t%29

when will the amount of investment be 

doubled? 2+=+%281.025%29%5E%284t%29, t = ln%282%29%2F4ln%281.025%29

tripled? t = ln%283%29%2F4ln%281.025%29
