Jane doe invested part of her $37,000 bonus in a fund that paid a 10% profit and invested the rest in stock that suffered a 5% loss. Find the amount of each investment if her overal net profit was $1,000.
---------
Quantity: t + f = 37000
Interest:10t-5f = 100000
----------------------------
Modify::
10t + 10f = 370000
10t - 5 f = 100000
------------------------
Subtract to get:
15f = 270000
-----
f = $18,000 (amt. invested at 5%)
----
Solve for "t:::
t + f = 37000
t + 18000 = 37000
t = $19,000 (amt. invested at 10%)
------------------------
