Question 1006153: Melissa is planning to invest a total of $17,000 in two accounts. If she invests $10,000 in a
CD paying 12% annual simple interest, at what rate does the remainder of her money need to be
invested so that the two investments together yield at least $1900 in yearly simple interest? (Set
up and solve an inequality to answer this question).

Let +r+ = the rate at which she must invest
the rest of her money
---------------------
++.12%2A10000+%2B+r%2A7000+%3E=+1900+
+1200+%2B+7000r+=+1900+
+7000r+=+700+
+r+=+.1+
+.1%2A100+=+10+
The rest of her money must be invested at 10% simple interest
