nd the system of equations to model the problem. DO NOT SOLVE THIS SYSTEM. 9) A $124,000 trust is to be invested in bonds paying 9%, CDs paying 8%, and mortgages paying 10%. 1 9) sum of the amount invested in bonds and the amount invested in CDs must equal the mortgage investment. To earn an $11,400 annual income from the investments, how much should the bank inv each? Let x represent the amount invested in bonds, y the amount invested in CDs, and z the amount inve: mortgages. A) x + y - z = 11,400 x - y + 9z = 22 8x +y +z = 124,000 C) x + y - z = 0 x + y + z = 124,000 0.09x + 0.08y + 0.1z = 11,400 B) x + y - z = 0 x + y +z= 124,000 9x + 8y + z = 11,400 D) x + y + z =0 x + y - 9z = 124,000 0.1x + 0.08y - 0.09z = 11,400
