The interest gained here is, of course, 54976 - 50000 = 4976
So now we set up our simple interest equations. we have two accounts, so we must have a sum of the two simple interests giving 4976
Thus we have:
so let's say the first account is the one that gives 5.2% interest. And let's say we invest dollars into this account. what do we have remaining? well, dollars, of course.
so our equation becomes:
now solve for , that will be the amount you invested into the first account. then subtract that answer from 50000 to find how much you invested into the second account
