<PRE><B>Question 468978</B>
A teacher has a choice of two investment plans an insured fund that has paid an average of 11% interest per year or a riskier investment that has an averaged a 13% return . if the same amount invested at the higher rate would generate an extra $120 per year how much does the teacher have to invest

-----------------------------------------
Let the investment amount  = x
----
0.13x - 0.11x = 120
---
0.02x = 120
---
x = $6000
