help on solving investment problem

Debra -You have two funds that add up to 8000, so let's divide it into two pieces:p and (8000-p)    These add up to 8000, right?One fund is at 5% and the other is at 7%, so this is written like this:p(.05) + (8000-p)(.07)      Make sense?Now, the total interest must equal $496, so here is the final equation:p(.05) + (8000-p)(.07) = 496Now just solve for p to get the fund invested at 5%, then (8000-p) is the fund invested at 7%.Hope that helps
