Answer:
She invested $2,167
Explanation:
As interest rate is not compounded, the 9-month interest of a 8% annual interest is simply:
8% * 9 / 12 = 6%
Let A be the amount of money she invest. After 9 month she will receive:
A * 0.06 dollars.
And the actual amount is $130. So she invested
A = $130 / 0.06 = $2,167
