A man had $12,000 to invest. If his income from a savings account earing 7.5% is $280.00 greater than his income from another investment at 8%, how much did he invest at each rate?
THANK YOU! :)

If he has $12,00 to invest, then the amount invested in the two accounts are X and 12000  X.
.075 of one plus .08 of the other = $280
You should be able to work it from there. I hope this helps. Thanks for asking.
