You can put this solution on YOUR website! a total of 11,000 was invested. part of the 11,000 was invested at 4%,
and the rest was invested at 7%.
if the investments earn 680 per yr, how much was invested at each rate?
:
Let x = amt invested at 7%
then
(11000-x) = amt invested at 4%
:
.07x + .04(11000-x) = 680
:
You should be able to do this now.
