Question 79681: Maxine invested $4000 in two accounts, one earning interest at 4% per year and the other at 2%. If his total interest for one year is $140, find how much she invested at 4%. Answer by checkley75(3666) (Show Source):
You can put this solution on YOUR website! .04x+.02(4000-x)=140
.04x+80-.02x=140
.02x=140-80
.02x=60
x=60/.02
x=3000 invested @ 4%.
proof
.04*3000+.02(4000-3000)=140
120+.02*1000=140
120+20=140
140=140
