you used A = P*(1+r)^t I bet huh?
jimthompson5910 (jim_thompson5910):
if so then you used the wrong formula
notice how it says "continuously"
jimthompson5910 (jim_thompson5910):
A = P*(1+r)^t only applies to annual growth or decay

:( Here we go again ! >.<
I used i= prt and that didn't work either!
jimthompson5910 (jim_thompson5910):
that's only for simple interest

You'd use A = P*e^(r*t)
OpenStudy (anonymous):
e?
jimthompson5910 (jim_thompson5910):
'e' is a constant like pi
e = 2.71828182846
and that expansion goes on forever without a known pattern
OpenStudy (anonymous):
Oh, that e- yes!! lol I thought you meant a variable..
jimthompson5910 (jim_thompson5910):
e is rarely (if ever) used as a variable
