Question 926516
Let {{{ P }}} = his investment
His return from 5% investment is:
{{{ (1/2)*P*.05 }}}
------------------------
His return from 4% investment is:
{{{ (1/3)*P*.04 }}}
--------------------------
His return from 3.5% investment is:
{{{ (1/6)*P*.035 }}}
-----------------
{{{ (1/2)*P*.05 + (1/3)*P*.04 + (1/6)*P*.035  = 795 }}}
Multiply both sides by {{{ 6 }}}
{{{ .15P + .08P + .035P = 4770 }}}
{{{ .265P = 4770 }}}
{{{ P = 18000 }}}
$18.000 was his investment
