Question 358362
debra invested $18000.Part of it was invested at 3% annual simple interest, and the rest was invested at 4%. Her interest income for the first year was $650.How much did she invest at each rate?
...
$x @ 3%
18000-x@4%
Interest = 650
...
3x+4(18000-x)=65000
3x+72000-4x=65000
-x=-7000
x= $7000 @ 3%
balance $11000 @4%
