Ok I'm not sure on how I would do the last bit of the equation but here's what I've got;
Answer 1= -8 = -3
Answer2= -8 - 3= -11
Not 100% sure on this. so, I'm sorry if its wrong
115 take the lowest number and the highest number and subtract so 135-20
Answer:
Step-by-step explanation:

Let x represent the amount invested at 8% (the highest rate). Then the total interest is ...
.08x +.03(3000 -x) = .04(3000)
.05x = .01(3000) . . . . subtract .03(3000)
x = 3000/5 = 600
Matthew invested $600 at 8%, $2400 at 3%.
