Question 1007151
{{{ S(t) = 5 + 29* ln ( t + 1 ) }}} 
{{{ 0 <= t <= 9 }}}
--------------
{{{ S(t) = 65 }}}
{{{ 65 = 5 + 29* ln ( t + 1 ) }}} 
{{{ 29* ln ( t + 1 ) = 60 }}}
{{{  ln ( t + 1 ) = 60/29 }}}
{{{ ln( t + 1 ) = 2.069 }}}
{{{ e^2.069 = t + 1 }}}
{{{ 7.917 = t + 1 }}}
{{{ t = 6.917 }}}
It will take 6.9 months
