Answer:

  $10,000

Step-by-step explanation:

Let b represent the amount invested in bonds. Then 50,000 - b wil be the amount invested in stocks. Molly's total return is ...

  0.15b + 0.18(50000-b) = 8700

  -0.03b +9000 = 8700 . . . . simplify

  300 = 0.03b . . . . . . . . . . . . add .03b-8700

  10,000 = b . . . . . . . . . . . . . divide by 0.03

Molly invested $10,000 in bonds.
