Let {{{ r }}} = the rate for the $800 investment
{{{ r + .04 }}} = the rate for the $2,000 investment
--------------
given:
{{{ 2000*( r + .04 ) = 800r + 146 }}}
{{{ 2000r + 80 = 800r + 146 }}}
{{{ 1200r = 146 - 80 }}}
{{{ 1200r = 66 }}}
{{{ r = .055 }}}
{{{ r + .04 = .095 }}}
The rate for the $800 investment is 5.5%
