Steve
well, yeah. solve the equation
If $x is invested at 15%, then the rest is invested at 10%. Add up the interest on each part,, getting the total interest.
.15x + .10(120000-x) = 5500
.15x + 12000 - .1x = 5500
.05x = -6500
WAK?!?!? x is negative?
Well, no wonder.
5500 is 4.5% of 120,000. There's no way she could have made between 10 and 15% on her investments and ended up with only 4.5% profit.
There's a typo in the problem, I fear.
