This one is in depreciation.. and leaving the one year one....... all need annually one..... the depreciation annually formula is
#p[1-r/100]^t#
where p is principal
r is rate
t is time
One year one
#10,500[1-15/100]^1#
Remember it is not necessary to use this formula.... as it's one year
#10,5cancel00xx85/(1cancel00)#
#105xx85#
#8925# is the value after one year
Two year one
#10,500[1-15/100]^2#
Notice not much has changed
#10,5cancel00xx(cancel85^17xx85)/(cancel100^20xx1cancel00)#
#105xx17xxcancel85^17/cancel20^4#
That gives us
#7586.25# is the value after two years depreciation
Now you get the drill..... Try to do it yourself
