Just did this last week. You take the anual interest formula
A(t)=a(1+r)^t and insert ur variables. 5500(1+.03)^t
t equals time so do the guess and check method to figure it out.
actually no. subracy 5500 from 22000 and then figure it out. ur
equation should look like this 16500(1+.03)^t and do guess and check.
If anybody knows any better methods write em down. im still a newbi at
this.
