A prfessor wants to supplement her pension with investment interst. If she invest $28,000 at 6%, how much more would she have to invest at 7% to achieve a goal of %3,500 per year in supplemental income?

28000(1.06) + x(1.07) = 3500
solve for x

just looked at my answer again, and it looks like I messed up
should have said:
28000(.06) + x(.07) = 3500
the answer is 26000
