Kitty invested money in stocks and bonds. The annual return on these is $605. If the stocks produce $155 more?

Question

than the bonds, how much money does John recieve per year from each type of investment?

Answer 1

let:
x= annual return on bonds
x+155=annual return on stocks

solution:
x+x+155=605
2x+155=605
2x+155-155=605-155 (subtract 155 from both sides)
2x= 450
x=225

answer:
annual return on bonds is 225 and annual return on stocks is 380

Answer 2

one makes 225, the other makes 380 annualy.
