Answer: She invested $34100 at 10% and $68200 at 6%.
Steps:
Let x1 be the amount invested at 6%, x2 the amount at 10%
After one year the simple interest is amount * (interest rate).
The total interest after one year:
7502 = x1 * 0.06 + x2 * 0.10
and we know that x1 = 2*x2
7502 = 2* x2 * 0.06 + x2 * 0.10 = 0.22 * x2
x2 = 34100
x1 = 2*34100=68200
