In particular, Ama, Fiifi and Ebo were able to negotiate 5%, 10% and 8% respectively on their investment. At the end of the year, 2018, the three siblings were able to earn a total interest of $600. In addition, supposed the amount of money given to Ebo is 300 more than the amount given by her two siblings combined. a) Write down the three linear equations. b) Represent them in the matrix form AX = B 8000 c) Find the determinant of the matrix A 600 d) Find the amount of money given to each of the 3 siblings using matrix inversion 300
