SA business student has \$2,500 available from a summer job and has identified three potential stocks in which to invest. The cost per share and expected return over the next 2 years is given in the table. a. Identify the decision variables, objective function, and constraints in simple verbal statements. b. Mathematically formulate a linear optimization model.

a) Let X1 be the quantity of stock A purchased, X2 be the quantity of stock B purchasd and X3 be the quantity of stock C purchased . The decision variables are X1 , X2 & X3   i.e. how much quantity of stock A , B & C should be purchased to maximize the returns of the investor . The constraint is the maximum money available with the investor to make the investment . The money available with the investor is \$ 2500 .

b) The objective is to maximize the returns and hence the objective function will be

Maximize Z = \$ 8X1 + \$7X2 + \$11X3

The constraint is the maximum money available with the investor to make the investment . The money available with the investor is \$ 2500 .

The constraint equation will be

\$25X1 + \$15X2 + \$30X3 $\leq$ \$ 2,500

X1 , X2 , X3$\geq$0
