Please show me how to work this one: A business club split a \$30,000 investment among three bond funds. The first one grew at 2%, the second at 3% and the third at 6%. The total earnings were \$1,110. The earnings from the second fund were \$150 more than those of the first. How much was invested in each fund?Answer by longjonsilver(2297)   (Show Source): You can put this solution on YOUR website!x+y+z = 30000 --eqn1 0.02x + 0.03y + 0.06z = 1110 --eqn2 0.03y = 0.02x + 150 --eqn3 OK... multiply eqn 1 by 0.06 then subtract eqn2, leaving 0.04x + 0.03y = 690 --eqn4 Now rearragne eqn3 around and then add it to eqn4, giving x = 9000. Then find y and z as per the other Q. jon.
