Question 1138904
{{{ P = P[0]*e^( .0265t ) }}}
{{{ P = 4P[0] }}}
{{{ 4P[0] = P[0]*e^( .0265t ) }}}
{{{ 4 = e^( .0265t ) }}}
{{{ ln(4) = .0265t }}}
{{{ 1.38629 = .0265t }}}
{{{ t = 52.313 }}} yrs
--------------------------
check:
{{{ 4 = e^( .0265*52.313 ) }}}
{{{ 4 = e^1.3863 }}}
{{{ 4 = 4 }}}
OK
check the math
