Answer:
It will take 25.28 year to have enough to buy the car ( ignoring Inflation effect)
Explanation:
Current Deposit = PV = $49,000
Future Value = FV = $199,000
Interest Rate = r = 5.7%
Use following Formula
FV = PV ( 1 + r )^n
$199,000 = $49,000 ( 1 + 0.057 )^n
$199,000 / $49,000 = ( 1 + 0.057 )^n
4.06 = 1.057^n
Log 4.06 = n log 1.057
n = log 4.06 / log 1.057
n = 25.28
it requires 25.28 year to have an amount to buy the Ferrari.
