Please help me answer this question: Kimberly invested $6000 in her savings account for 7 years. When she withdrew it, she had $7883.40. Interest was compounded continuously. What was the interest rate on the account?
--------------
A(t) = Ao*e^(rt)
-----
7883.4 = 6000*e^(7r)
-------
e^(7r) = 1.3139
7r = ln(1.3139
rate = 0.039 = 3.9%
