x and y are the proportions in each account
like if you had 1000 in one account and 2000 in the other account
so x = 1/3 and y = 2/3 (just an example)
x+y = 3000
0.05*(x/3000) + 0.09*(y/3000) = .075
i think that is right...

i choose you purely like the river needs their shorelines, and the birds their nest the king a kingdom i choose you want a drop of water needs yet another drop of water to grow to be a pass of water like the window needs the wall Like your hart can no longer with out forgiveness Like a wound can no longer heal and not using a hand like the smash out needs the terror needs the fireplace the flame. -R.
