<PRE><B>Question 1128550</B>
 Alice invests $18,000 at age 30 from the signing bonus of her new job. She hopes the investments will be worth $36,000 when she turns 41. If the interest compounds continuously, approximately what rate (as a percent) of growth will she need to achieve her goal? 
------
A(t) = P*e^(rt)
36000 = 18000*e^(r*11)
e^(11r) = 2
----
11r = ln2/lne
11r = 0.693
r = 0.063
Answer:: rate = 6.3%
--------
