a) For the context below, define a set of 3 variables, write an appropriate system of equations, and write the system in a matrix form. b) Solve the matrix system by a method of your choice and interpret your answer in the context of the problem. Jaylen invested $8000 in three different mutual funds. One fund containing large cap stocks made 6.2% return in a given year. A real estate fund lost 13.5% in that same year, and a bond fund made 4.4% that year. The amount invested in the large cap stock fund was twice the amount invested in the real estate fund. If Devon had a net return of $66 across all investments, how much did he invest in each fund?
