<PRE><B>Question 519987</B>
Money invested at 8% = x
Money invested at 6% = 7000-x
Total interest from both investements = 500

Money invested at 8% * Interest + Money invested at 6% * Interest = Total interest from both investements



x*8% + (7000-x)*6% = 500
x*0.08 + (7000-x)*0.06 = 500
0.08x + 420-0.06x = 500
0.02x=500-420
0.02x=80
x=80/0.02
x=4000


Money invested at 8% = x = $4000
Money invested at 6% = 7000-x = 7000-4000= $3000


Check
=====
4000 * 0.08 + 3000 * 0.06 = 500
320 + 180 = 500
500 = 500</PRE>
