12.​ You has investments totaling $8000 in two accounts: a savings account paying

5% interest, and the other a bond paying 8% interest. If the amount of interest after

one year from both investments was $600, how much did you invest in both accounts

initially?

1 answer

let x = amount in savings
8000-x = amount invested
--------------
0.05x + 0.08(8000-x) = 600
Solve for x and 8000-x
