Credit union regulations require diversification to the extent that at least 40% of the investment be placed in Treasury notes. It is also decided that no more than 30% of the investment be placed in bonds 250- The aim of the objective function for Rio Credit Union should be to the objective value 200 Decision variables: X = $ invested in Treasury notes Y = $ invested in Bonds Objective function (in decimals, eg., 07.
