Answer:

  • at 5.4% — $10,000
  • at 8% — $5000

Step-by-step explanation:

It is convenient to use a variable for the amount invested at the higher rate. If that variable is x, then the amount invested at the lower rate is (15000-x) and Anna's total annual interest is ...

  0.054(15000 -x) + 0.08x = 940

  0.026x +810 = 940

  0.026x = 130

  x = 130/0.026 = 5000

Anna invests $5,000 at 8% and $10,000 at 5.4%.
