Problema Solution

The value of a particular investment follows a pattern of exponential growth. In the year 2000, you invested money in a money market account. the value of your investment t years after 2000 is given by the exponential growth model A=6500e0.064t. When will the account be worth $10,174?

Answer provided by our tutors

A(t)=6500e^(0.064t)

We need to find t such that A(t) = $10,174 that is:

6500e^(0.064t) = 10174

e^(0.064t) = 10174/6500

........

t = 7 years

7 years after 2000 is 2007

In the year 2007 the account will be $10,174 worth.
