Write the system of equations only. Do not solve. An investment firm recommends that a client invest in bonds rated AAA, A, and B. The average yield on AAA bonds is 4%, on A bonds 8%, and on B bonds 12%. The client wants to invest twice as much in A bonds as in B bonds. How much should be invested in each type of bond, if the total investment is $24,000, and the investor wants an annual return of $1740 on the three investments? Let x be the number of AAA bonds, y the number of A bonds, and z the number of B bonds. x+y+z=24,000 4x+8y +12z = 17,400 -2z=0 x+y+z=24,000 4x+8y +12z = 174,000 x-2z=0 √x +y +z = -z = 24,000 4x+8y +12z = 174,000 ly-2z=0 x +y +z = 24,000 4x+8y +12z = 174,000 2y-z=0
