Find the system of equations to model the problem. DO NOT SOLVE THIS SYSTEM. A $124,000 trust is to be invested in bonds paying 9%, CDs paying 8%, and mortgages paying 10%. The 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 invest in each? Let x represent the amount invested in bonds, y the amount invested in CDs, and z the amount invested in mortgages. O A. x+y+z=0 x+y-9z=124,000 0.1x+0.08y-0.09z = 11,400 OC. x+y-z=0 x+y+z=124,000 0.09x +0.08y +0.1z=11,400 C OB. x+y-z=0 x+y+z=124,000 9x+8y +z = 11,400 O D. x+y-z=11,400 x-y+9z=22 8x+y+z=124,000
