Find the value. Give an approximation to four decimal places.
-The logarithmic function $f ( x ) = - 100 + 87 \ln x$ models the number of visitors (in millions) to a certain country's museums, where $x$ is the number of years since the initial recording of the number of visitors. Use this function to estimate the number of visitors in year 60 . Round to the nearest tenth of a year.
A) $384.3$ million
B) $256.2$ million
C) $192.2$ million
D) $128.1$ million
