Question 51845
An investor plans to invest part of 5,000$ in a stock that pays 8% interest annually. The rest will be invested in a savings account that pays 6% interest annually The investor wants to make at least 350$ on the investment for the first year. What is the least amount that should be invested in the stock.
--------------------

Let amount invested at 8% be "x".
Interest on this money will be 0.08x dollars.
Amount invested at 6% will be "5000-x"
Interest on this money will be 0.06(5000-x)= 300-0.06x dollars
INEQUALITY:
interest + interest >=350 dollars
0.08x +300-0.06x>=350
8x+30000-6x>=35000
2x>=5000
