An individual plans to invest $2,000 in a portfolio consisting of Stock A, Stock B, and Stock C. Stock A has an expected return of 8%, Stock B has an expected return of 12%, and Stock C has an expected return of 20%. If the individual plans to invest twice as much money in Stock B as in Stock A, use MATRIX ALGEBRA to determine how much money will be invested in each of these three stocks if the portfolio expected return is 16%.
