Amount required in 18 years = $300,000
Amount invested today = $45,000
Period of investment = n = 18
Let the annual rate of interest = r
Future value of investment = Amount invested*(1+r)n
$300,000 = $45,000*(1+r)18
(1+r)18 = $300,000/$45,000 = 6.667
1+r = 6.66671/18
r = 1.1112 – 1 = 0.1112 = 11.12%
Hence, correct answer is 11.12%
