Question 417466
Let {{{x}}} = amount invested @ 6%
given:
{{{4x}}} = amount invested @ 5%
-------------------------
{{{.06x + .05*(4x) = 525}}}
{{{.06x + .2x = 525}}}
{{{.26x = 525}}}
{{{x = 2019.23}}}
{{{4x = 8076.92}}}
She invested $2019.23 @ 6%
She invested $8076.92 @ 5%

{{{.06x + .05*(4x) = 525}}}
{{{.06*2019.23 + .05*(8076.92) = 525}}}
{{{ 121.15 + 403.85 = 525}}}
{{{ 524.996 = 525}}} (close enough)
