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 ...

-0.03b +9000 = 8700 . . . . simplify
300 = 0.03b . . . . . . . . . . . . add .03b-8700
10,000 = b . . . . . . . . . . . . . divide by 0.03
