Answer: I must invest $85424.14 today in order to buy a Ferrari nine years from now on the day I turn 30.
We have
Price of the Ferrari nine years from now (Future Value - FV) $215000
Expected Rate of return on the mutual fund (r) 10.8%
Time until I turn 30 (n) 9 years
We can calculate the Present Value (PV) or the money to be invested today as
![\mathbf{PV = (FV)/((1+n)^(n))}](https://img.qammunity.org/2019/formulas/business/college/ols9qyg4oi4nmd5njon2rxjswx19v40kkr.png)
![PV = (215000)/((1+0.108)^(9))](https://img.qammunity.org/2019/formulas/business/college/jd1p8ihbqunrlplc1loztwb4j16p7x4gql.png)
![\mathbf{PV = 85424.14022}](https://img.qammunity.org/2019/formulas/business/college/ro6qj2nxh1wxge5de135raw6ze1j4v60ua.png)
