Question 644327
Let {{{ x }}}| = amount invested at 4%
{{{ 2x }}} = amount invested at 5%
given:
{{{ .04x + .05*2x = 1960 }}}
{{{ .14x = 1960 }}}
{{{ x = 1960 / .14 }}}
{{{ x = 14000 }}}
{{{ 2x = 28000 }}}
$14,000 is invested at 4%
$28,000 is invested at 5%
check:
{{{ .04x + .05*2x = 1960 }}}
{{{ .04*14000 + .05*28000 = 1960 }}}
{{{ 560 + 1400 = 1960 }}}
{{{ 1960 = 1960 }}}
OK
