Transcribed Image Text:Investor Matt has $83,000 to invest in a CD and a mutual fund.
The CD yields 4% and the mutual fund yields an average of
8.5%. The mutual fund requires a minimum investment of
$10,000, and Matt requires that at least 2 times as much money
be invested in the CD as in the mutual fund. You must invest in
these bonds to maximize his return.
This can be set up as a linear programming problem. Introduce
the decision variables:
X dollars invested in the CD
=
Y dollars invested in the mutual fund
-
Check all of the problem constraints. Note: The non-negative
constraints are not included here.
