Solution

let the amount invested in Treasury bills = x

then amount invested in corporate bonds = x/2

amount invested in treasury bond = 50,000 - ( x+x/2) = 50,000 - 3x/2

treasury bills that yield 3 %, Treasury bonds that yield 6 %, and corporate bonds that yield 9 %.

equation becomes

.03x + .06( 50,000 - 3x/2 ) +.09 x/2 = 2970

.03x + 3000 - .18x / 2 + .09x/2 = 2970

.06x/2 - .18x/2 +.09x/2 = 2970 - 3000

-.03x/ 2 = -30

x = 2000

treasury bill = $ 2000

corporate bonds = $ 1000

treasury bond = 50,000 - ( 3*2000/2 ) = $ 47000

there is one solution
