Question 229084
<font face="Garamond" size="+2">


Let *[tex \Large x] represent the amount invested at 8%, then *[tex \Large 2x] is the amount invested at 10%.  So:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 0.08x + 0.10(2x) = 224]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ .28x = 224]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x = 800]


$800.00 @ 8% = $64.00 and $1,600.00 @ 10% = $160.00.  $160.00 + $64.00 = $224.00
