Question 1184102
<br>
x = amount invested at 6%
x+6000 = amount invested at 7%<br>
Total interest was $680:<br>
{{{.06(x)+.07(x+6000)=680}}}<br>
I personally would multiply by 100 to get rid of the decimals...<br>
{{{6x+7(x+6000)=68000}}}<br>
You can finish from there....<br>
(final answers: $2000 at 6%, $8000 at 7%)<br>
