    You invested $x at 8% You invested $(100-x) at 6% formula for simple interest: A = P(1+in) I believe you should be able to do it now

    (1000-x)*8%+x*6%=76 solve to get x and you wil have the answer

    Most investment questions ask what is the interest, but this one is throwing me off cause the interest is already given.
