Question 334801
Let A be the amount at 7%, B the amount at 6%.
1.{{{A+B=5000}}}
.
.
.
{{{(7/100)A+(6/100)B=332}}}
2.{{{7A+6B=33200}}}
From eq. 1,
{{{A=5000-B}}}
Substitute into eq. 2,
{{{7(5000-B)+6B=33200}}}
{{{35000-7B+6B=33200}}}
{{{-B=-1800}}}
{{{B=1800}}}
Then from eq. 1,
{{{A+1800=5000}}}
{{{A=3200}}}
.
.
.
$3200 invested at 7%, $1800 invested at 6%.
